Tickletober Day 5: Sneak Attack/Scare

They did NOT expect to be playing the same prank on each other. Neither are complaining, though… 💕

Sans starts to learn the differences of intent between playful tickles and roughhousing, and how his bond with the tickler affects the experience. Still, at this point, he's processing strong and confusing feelings for what he believes to be torture.

[haveyouseenthisskeleton]

You know how all skeletons technically have a tailbone? What if skeleton's toddler just randomly grab it while his dad is talking with someone?

Undertale Sans - He's chill, simply squirming to get the kid to let go. The tailbone is actually very sensitive for skeletons and he would greatly appreciate them stopping to shake it like a coconut. Sans grabs their hand and gives them short black eye sockets to shoo them away. It's effective. No one likes Sans' black sockets.

Undertale Papyrus - His voice suddenly turns very high-pitched as he jumps in surprise. He turns around and asks his kid to please not do that. The kid thought his voice was hilarious though and just waited for his dad to look away to do it again. Papyrus is getting so teased by Undyne the rest of the week.

Underswap Sans - He instinctively slaps whatever is touching THERE and realizes only after it is actually his toddler, who's now crying on the floor. Well great. Blue panics, trying to get them to calm down before they go snitch to his S/O.

Underswap Papyrus - He jumps in surprise, trips on a random lego, and then faceplants into the floor in front of a very confused Undyne. His toddler bursts into laughter and climbs on his back, asking him to do it again. Honey stays on the floor. Maybe it will absorb him or something. He's so embarrassed right now.

Underfell Sans - "ya cutting your bullshit right now or i'll do it to you to see how fun it is." That's for sure have no effect on his child who immediately grabs his tailbone again :D S/O enters the room to find his child screaming and trashing in the air while Red holds them above the ground by the tailbone, asking them how it feels now. Red then notices his S/O and very slowly puts the child back on the floor. Uh oh. He's in trouble, isn't he?

Underfell Papyrus - He throws Doomfanger in the air in surprise. The cat panics and jumps at Undyne's face, all claws out. While Undyne is struggling for her life, Edge turns around and starts to lecture his child about grabbing people's tailbone. You don't do that or people get hurt! Look at that, Aunt Undyne is getting absolutely destroyed by your fault! That doesn't mean Edge is going to help her though.

Horrortale Sans - He actually fell on his tailbone a lot when he had to learn how to walk again after Undyne exploded his head, so he has no sensitivity whatsoever in this part. He's actually surprised when Toriel says they're kid is pulling his tailbone. He blinks at them for a few seconds, then just shrugs. They seem to have fun.

Horrortale Papyrus - He randomly screams in the middle of his sentence and drags his kid by the arm in front of him. Better. Now stay where he can see you. He doesn't trust his child behind him ever again lol. He would prefer them not to try to hang to his tailbone as they are easy and it would hurt his back.

Swapfell Sans - He hisses and jumps so high he actually ends up on the top of the couch. He then blushes furiously as the Queen stares at him in complete disbelief. Oops. Yeah, maybe it was not a good moment to do that. He was surprised. S/O comes to his rescue and drags the child out of the room to prevent other diplomatic accidents.

Swapfell Papyrus - It's one of his ticklish weak points. He's trying really hard to keep a straight face, but eventually, he starts to laugh uncontrollably, trying to make his kid let go. His brother is staring at him, very concerned about him at the moment, wondering what just happened. Rus can't even explain. He's out of breath, trying to recover. Nox can't see the child so... He's concerned.

Fellswap Gold Sans - He suddenly straightens, twitching as he struggles to keep a straight face. He asks for the Queen to excuse him for a minute, then turns around, grabs his kid, throws him in the closet, and closes the door. Dad needs a moment to recover. Toriel is that close to calling social services honestly.

Fellswap Gold Papyrus - He yelps in the middle of the conversation, then flushes as both his brother and Alphys are now staring at him in complete silence. Wine asks if he's fine, he just nods eagerly, then runs out of the room, his kid still holding his tailbone firmly and refusing to let go. He's going to ask help to his S/O.

Nothing scheduled today, Papyrus finally taking a day off to hang out with Undyne... Yup. Today was the best day to relax... A day to just be even more lazy, a da- "Sans!" someone shouted, bursting through the door. Oh, it was Frisk.

"oh, wassup?" Sans waved.

"I called you five times already and you didn't pick up or reply to my texts!!!" Frisk exclaimed.

"oh sorry. left my phone upstairs heh."

"Well grab your phone and let's just get going already I guess."

"going where?"

"To the study lounge outside the library you bonehead. Did you forget about our meet up?"

Oh, right! He knew he was missing something today. "ah... ok, give me a moment." Sans said, before teleporting upstairs to grab his phone. "ok i'm ready, let's go frisk."

"Aren't you gonna teleports us there since we're already 25 minutes late?" Frisk questioned.

"oh right, forgot I could do that heh."

Sans held out his hand as he spoke. Frisk rolled her eyes in amusement and grabbed it.

The study lounge usually didn't have many people since the library had aircon while the study lounge didn't. Both of them usually chose that spot since Frisk always felt the library was too cold. Moreover, they kinda liked the privacy the place provided. The best place to study without any disturbance.

As time flew by, sans stumbled across something peculiar to him. "hey frisk? can I comfirm something?" Sans tapped Frisk's shoulder.

"Yeah?"

"this book states humans have 12 pairs of ribs... is there a typo? or is it true."

"It's not wrong. Why? Do you have a different number of ribs?"

Sans looked a little surprised, "well yeah. I only have 10 pairs... weird. humans are weird."

"Pff- says the guy that's close friends with a human. Anyways, would it be fine if I checked to see if you really have 10 pairs of ribs? I'm curious now." It was interesting to Frisk how human anatomy and skeleton monsters were so similiar yet so different. But technically skeleton monsters weren't exactly skeletons from humans so it made sense.

"uh well I rather not do it in public.. you know" Sans commented.

"Oh, no, I didn't mean show it to me, I can just try feeling it through ur clothing if that's alright with you."

"well, if that's the case then it's... fine, just do it."

"You sure? I wouldn't want to do something your not comfortable with."

"nah, it's fine. I'm okay with it."

Well... If he said it was alright then alright. Frisk started slowly moving down Sans ribs, counting slowly as she made her way down. All the while, she was oblivious to Sans. There was a reason why he was hesitant.

Sans could feel the slight laughter threatening to slip out. He had to use all of his will power to not move or make any sudden twitches. That, and the fact that he was trying not to grin like an idiot even though it was fruitless.

"snrk-!" it slipped. Welp, all of his efforts were in vain because of that one slip up.

"Uh Sans? You alright? I heard you-" Frisk stopped as she scanned Sans's half covered face. After a few seconds, it clicked. "Oh wait... Are you, ticklish?" Frisk then started scribbling a little harder.

This time Sans pushed on her arm, clearly knowing she was doing it on purpose now. "kh! w-wahait we're a-hat the st-studehe lounge n-now. Theherse p-people studying." Sans stuttered, trying to control his laughter from pouring out.

"Okay, I guess I can lay off this new discovery. For now." Frisk snickered and stopped. "Don't think for a second I'm letting this off though."

Sans whimpered. Time to stay in his room for the next few years. "can we jus get back to reading...?" He pleaded

Frisk gave him a thumbs up and continued to read up on how human souls worked. Occasionally chuckling as she saw Sans ever so often darting his eyes towards Frisk and back to his book.

A few days after the incident, Frisk had planned to have a sleepover at the brothers' house. It was always a blast when the two were around. She couldn't wait to finally relax after studying for one whole week, straight.

Ding! The doorbell sounded. Papyrus was cooking up some lunch, which was finally something other than spaghetti, so he couldn't get the door. "SANS! Can you get the door for me?" Papyrus exclaimed from the kitchen.

"ok" Sans replied, as always.

"oh, sup." Sans greeted Frisk.

"Hey Sans. The food actually smells good for once. Papyrus's been taking classes?" Frisk asked.

"yup. wannna stay in my room while we wait?"

"Sure!"

Frisk stated walking up the stairs to Sans's room, only to find out he had taken a shortcut up there. Typical Sans. When Frisk opened the door, as usual, it was a mess. His bed was no more than a mattress on the floor, with a table, a beanbag and a chair beside it. On the table there was a few sketches and books layed out in a pile. Near the entrance to the right, there was a bookshelf full of science books and a few new additions from the last time you visited. Frisk could see Sans sitting comfortably on the beanbag reading a book. As if he had been waiting for Frisk for a long time.

"so, i've recently been reading more about humans. gotta say, pretty weird. guess that's why you were so confused on how i worked, with how all your organs work and stuff." Sans had always thought humans worked similiar to monsters. Sure, he knew they were different, but he didn't know they were extremely different. They did have souls anyways, though he hadn't found a book talking much about human souls which was unfortunate.

Frisk walked over and sat on the chair, all while listening attentively to what Sans had to say. "Yeah, just like how I was surprised you only had 10 pairs of ribs. Speaking of which, I haven't really gotten the chance to count them since last time, have I? And I still have my doubts..." She chipped in.

Sans eyes widened for a brief moment before eyeing Frisk, "d-don't you dare."

"I am also kind of curious how you manage to feel without nerves... I might need to conduct an experiment to find out." Frisk continued.

At this point Sans had wrapped his hands around his sensitive ribs, zipping up his jacket. However, Sans did have a trick up his sleeve to counter Frisk's attack. He did have a knack for observing expressions to tell what their next move would be. In addition, while Frisk was still babbling on, now would be the best time to strike. Now just any attack though, a surprise attack. He could teleport and he was going to use it to his advantage. And that was what he did.

However, Frisk knew, she knew that Sans would retaliate. So the moment he teleported, she turned behind her, expecting to catch him off guard. Though, she was the one who got caught off guard. Sans being Sans, knew full well that Frisk expected something like that. So instead of teleporting behind her, he teleported in front of her. Sans then engulfed Frisk into a bear hug and digged into her sides. Frisk yelped and tried to get away but Sans grip was too strong. Who knew he could actually be decently strong? "!? SAhAnnNs aha! Pfhaaha waahaaittt!"

"you were the one who started this frisk, heh."

No! Frisk couldn't let a silly skeleton overpower her. She had to retaliate! Among her struggles, she managed to catch a hold of Sans's wrist. With much effort, she finally turned the tables. Frisk pulled one of Sans hands above his head and scribbled on his ribs. "crahahaap! frihiskk nohoo, ahem sorrhee!! nahaa-" Sans flailed. Guess he hadn't though that Frisk could get the upperhand so quickly. He should have used his gravity magic on her.

"I started this and I plan to finish it!" Frisk exclaimed. "Now let's see.. How many ribs... 1, 2.."

No matter how Sans struggled and pushed, he couldn't get rid of Frisk's teasing fingers. "aeheh alreheady tohold yaha it wahaaas 10 pahahairrss!!! staaaahaap ghaaha!" Sans tried teleporting or using his magic to push frisk away, but he couldn't focus enough to use it. His magic, though was very powerful, was not trained enough. Damn, he should start training with Pap if this was going to be a thing that Frisk would do now. Now that was a joke of course, he probably would just practice dodging instead.

"Well, I still need to make sure don't I~? 6...7.." Frisk teased.

"thihis iss juhuust cruhuehel- nohooo nahaht theeheere!!!" Sans snorted. "ghaahaha plheheaasee!-" The poor guy kicked and flailed but nothing helped. Uncontrollably laughter continued to pour out.

"Juuust a little more~ I could always go faster~~" Frisk cooed "10..11..12.."

"wahaahait! nahaahaa dohoon't, ahaa! cohome ohonn-"

After what seemed to be an eternity for Sans... "And... 20!" Frisk release the poor guy.

"hff.. hf.. thahnk g.. hff god." Sans panted, slumping to the ground. He lied on his back, facing the ceiling as he closed his eyes.

"Pfft. You alright there Sans?" Frisk chuckled. She handed Sans a bottle of water she found on his desk.

Sans nodded, accepting the water and gulping it down. Afterwards, he looked up at his alarm clock. Damn, it had only been 7 minutes and he was already tired. However, he still had some energy... And he knew exactly how he was going to use it. After a few minutes of chilling in Sans room, the both of them heard Papyrus call them for lunch.

As they walked out, Sans called out to Frisk. "Yeah?" She responded. Sans was about to speak, but stopped himself.

Instead, he replied, "uh nevermind. i wanted to tell ya somethin' but i forgot heh."

Frisk gave him a confused look but continued walking down the stairs. Sans being Sans. When Frisk turned towards the stairs, Sans casual grin turned into a smirk. Guess Frisk forgot that Sans has a tendancy to side with justice.

Do you base your Mettaton only on canon or do you have any favorite headcanons borrowed from fandom. Like, do you have any voices (voiceactors etc) that you think are perfect for him?

I'm not just asking about MTT, but about other UT/DR characters as well!

I mostly (try to) base him on canon, although I have so many headcanons about him now that he's basically my own character haha. Mostly stuff taken from my dreams or own ideas tho, I don't really tend to borrow unless it fits my very specific vision that I developed for him. But I do have a few headcanons that I borrowed from others. Like the plug tail. Or that he tastes make-up, nailpolish and hair products to test their quality. Or that his eyes flash red when he's angry. Or that he's aro and pansexual, although idk if I borrowed that.. I think it's actually my own. I just didn't really think about it until I saw other people bring it up as well. Hm. Or that he can feel ALL of his mechanics cause he like. literally became his body. Or that he's ticklish. Those two may or may not correlate. Or cooling fans. Sort of like the ones computers have. As in, instead of blushing his fans start to whirr to try and cool him down. I've seen it in some fanfictions and since it appeared in one of my dreams too it's basically canon to me.

As for the voice.. In Mettaton's case, I got a rather complex, VERY specific headcanon voice for him (mostly based on what he sounds like in my dreams) and I haven't heard anyone sound close enough to it. As for the other UT characters, I conducted a research (stole other people's headcanons basically xD), and made a list of voice(actor)s for them, behold:

Flowey: Kotetsu from Kamisama Kiss (Josh Grelle) Toriel: Kala from Tarzan (Glenn Close) Sans: Patrick Seitz. Papyrus: Alan Oppenheimer Undyne: Lalaco Godspeed from Space Patrol Luluco (Monica Rial) Alphys (not really but eh,): Lara Jill Miller Mettaton (ex) (take with a grain of salt, it's the closest I found to my headcanon anyway): Zarbon from Dragon Ball Raging Blast (J. Michael Tatum) (also James Carter Cathcart kinda) Asgore: King Frederic from Rapunzel's Tangled Adventure (Clancy Brown) Asriel - young: Armin Arlert from Attack on Titan (Josh Grelle) - adult: Xbalanque from SMITE (Josh Grelle)

Burgerpants: Sanji from One Piece Film: Gold (Eric Vale) Bratty: Kobayshi from Miss Kobayshi's Dragon Maid (Lean Clark) Catty: Junko Enoshima from Dangaronpa 3: The End of Hope's Peak High School (Jamie Marchi) Snowdin shopkeeper: Shion Kananomori from Psycho-Pass (Lydia Mackay) Gerson: Kaseki from Dr. Stone (Kenny Green)

They're colour coded so you can see where exactly I stole what from where, and to hear it too, if you want:

Green (timestamps) Flowey - 0:00 Undyne - 2:11 Mettaton - 3:47 Snowdin shopkeeper - 7:34 Gerson - 8:30 Bratty - 9:04 Catty - 9:30 Burgerpants - 10:03 Asriel (adult) - 10:36 Asriel (young) - 11:09

Red Toriel - 0:24

Blue Alphys - 0:22 Mettaton #2 - 0:35 Asgore - 1:32 Papyrus - 2:49 Sans - 3:01

As for the DR characters.. Dunno, I didn't really look into it. When it comes to Spamton, my headcanon voice(actor) for him is Alex Rochon ig. For the others- L Void cuts it for me just fine. Especially for Queen, Susie and Kris. Although for Berdly and Jevil it'd be Revtrosity instead.

I can't bother with links there, too lazy.

My GAHD this brings me back to my Undertale days. And as far as the tickle community goes, here are some common tickle prompts from that era:

-Sans being the most ticklish person in the entire fucking underground

-Papyrus ticklish on his spine (Sans is revealed to be the same way)

-Toriel’s ticklish horns

-Asgore being barely mentioned in the tickle community

-Flowey being the most TERRIFYING LER IN THE ENTIRE UNDERGROUND…his overpowered vines…grumble, grumble

-Flowey being pretty much NOT ticklish, but Asriel being really ticklish

-Chara being the second most terrifying ler

-Chara being barely ticklish at all

-Gastor and his ticklish elbows, of all things

-Sans inventing the BLANKET MONSTER and capturing the people around him, tickling them under the blanket!! I LOVE this idea! I have since I learned about it!!

-Muffet’s ticklish feet

-Sans using his Telekinesis to lift up the monsters, freeze them in place and tickle them silly

-Gaster using his telekinesis to tickle Sans and Papyrus (he’s basically their dad half the time.)

-Grillby tickling Sans for fun/because he won’t pay his FUCKING TAB

-Sans and Papyrus being tickled by their Gaster Blasters.

-Alphys being a bit of a switch. She either tickles the monsters because of SCIENCE! Or she is tickled by Undyne (or Sans, for some reason)

-Asriel growing extremely terrified of Ler!Chara

And lastly:

-Sans and Papyrus being able to remove their limbs and throw them around. But Sans being able to remove Pap’s foot, tickle it and make Papyrus laugh despite the foot being detached.

some of my favorite trends in Undertale fanart:

papyrus’ jaw sticking out at odd angles when he’s yelling

mettaton hugging people by wrapping his noodle arms around them like 34 times

sans with a definite belly, no explanation given

frisk using asl (and all the monsters understanding it)

that post-pacifist au where frisk keeps flowey in a flowerpot and he’s just a whiny little shit

toriel with a slightly dragon-like appearance

sans hiding things in his jacket

papyrus and toriel picking sans up when they hug him

papyrus being amazing at helping people thru panic attacks

undyne with impossibly long flowing hair

undyne’s “hair” actually being a fin

sans with a gap in his front teeth

alphys’ pudgy little tail

mettaton/napstablook bonding

mettaton/frisk bonding

chara as the provider of the game’s flavor text

sans treating the gasterblasters like pets

sans instantly falling asleep in weird places (usually papyrus’ arms)

god of hyperdeath = asriel’s totally original OC do not steal

asgore hastily naming asriel by mashing together his and toriel’s names

gaster being really sweet and gentlemanly before The Accident

[secrettklstories]

Papyrus is abducted and experimented on by aliens!

But...something about these aliens feels a little familiar! XD

Words cannot express just how lucky I was to get this done on time ^_^

May I please get some cute Honey head cannons 💕 maybe some favorite memories of his or funny moments he likes?

When honey was a baby, he used to try to copy everything Star did. He would even copy his brothers Mwe he he laugh and his heroic poses. Alphys and undyne thought it was the cutest thing ever and would steal him away from Star to dress him up in a matching battle body they made. Baby honey loved the attention naturally

He’s normally not that clumsy, but honey stands no chance against ice. It’s why he wears cleats in the winter lol. There’s been multiple times where he’s slipped into strangers arms. He even had some teen use the “looks like you fell for me” line. Honey was mortified lol

Honey as a dad and honey as a babysitter are two different people. He’s much more strict with his own kids, but when he’s babysitting it’s pizza and movie night lol.

He’s pretty ticklish on his neck and when he laughs he can’t move. If his SO ever feels like torturing him, this is how they can do it.

Honey loves hearing his SO geek about their fandoms/favorite characters. He’ll just happily sit there with his face all flushed and little hearts in his eyes as he listens. If they ask him any questions, he’ll try to cover up the fact that he wasn’t paying attention by telling them how cute he thinks they are. And now both honey and SO are blushing ;)

O Christmas Bones

Sans and Papyrus… "O Christmas bones, O Christmas bones, how ticklish are these boneheads?" Lol XD Merry Christmas, everyone! :D A few days late, I know but better late than never, right? Haha! Anyways, as my contribution to the holiday of Christmas, here is a request I did for RainbowRose85 on Wattpad. She wanted a story about the Skelebros being tickled by a certain someone and I felt that a Christmas setting would be fun for them (and us too, hehe). And like "Tickle Me Azzy," the first Christmas story I wrote, this story takes place 14 months after the events of Undertale and 7 months after my most recent main series story, "W.D. Gaster, the Best Uncle Ever Part 1." Come to think of it, you could actually consider this story a sequel to “Tickle Me Azzy,” since it takes place one day later. ;)

 O CHRISTMAS BONES

 It is December 23, 8:00pm, two days before Christmas, and at this very moment, Sans and Papyrus are relaxing in their living room. Earlier today, thirteen children (Ebott Junior High School students Frisk, Chara, Asriel, Perry, Heather, and Bastian and Ebott Elementary School students MK, Brad, Justin, Izzy, Patty, Kyle, and GK) came over to their place and used their backyard for some winter-related activities; with their permission, of course. Before spending the following two days with their respective families, the thirteen kids wanted to first spend some time with one another as well as the Skelebros themselves. With six of the thirteen kids in middle school now and thus in a different building entirely, they all don't get to hang out together during lunch and recess like they used to. But they can still hang out together outside of school and perhaps the best place for winter-related activities aside from Ebott Elementary School (there are hills next to the school grounds) is the Skelebros' home. Even better because besides hills behind their house for sledding and a large wide open space at the bottom of the hills for snowball fights and building snow forts, they also have an outdoor hockey rink! :D That's right; somewhere down the hill behind the Skelebros' house is a hockey rink that can be used to play hockey or just ice skate in general. The Main Six (Toriel, Asgore, Sans, Papyrus, Undyne, and Alphys) played hockey in this rink last winter and their game attracted the attention of some weirdo enough to hide somewhere out of sight and watch them play. Then for some strange reason, after watching the Main Six play hockey, this weirdo felt the need to write a super inaccurate article about their hockey game and the Main Six themselves and then post it online for the entire town; no, the entire world to see without their consent. Undyne believing that she had to tackle the player with the puck, a little white dog joining the game and scoring more goals than everyone, Sans and Toriel hitting each other's sticks and acting like they didn't know how to play hockey, Papyrus's believing that the power of friendship was required to score goals, Alphys watching videos on her phone midgame, Asgore falling through the ice, Sans doing a cringy victory dance every time he scored a goal, etc.; all false information! XD But today however, the thirteen kids (and Sans because they needed an extra player to even out the teams and it worked out perfectly since Sans is around the same height of a preteen child), with Papyrus as the referee, played a game of hockey together. The seven young boys faced off against the six young girls and Sans, who had on a pink jacket, pink knee-length dress, pink stocking hat, and a red wig at the time. Sans was on the girls' team so he thought it would be funny if he dressed and acted like a girl. XD And it was too! The way Sans "flirted" with the boys had everyone in stitches. Even Papyrus! XD As for the hockey game itself, it was a close game! The girls and Sans beat the boys by just one point! ;) But playing hockey was just one of several winter activities the kids all did together. Besides hockey, they went sledding and snowboarding on the big hills, did some ice skating outside of the hockey game, built snowmen and snow forts, made snow angels, and engaged in some rather epic snowball fights. And they all dressed accordingly too; wearing stocking hats, mittens/gloves, scarves, coats, and snow pants. And unlike Asriel, MK, GK, Heather (a 13-year-old rabbit monster and Brad and Justin's older adopted sister), and Bastian (a 12-year-old rabbit monster and Izzy's older adopted brother), the five monster children and barefooters with extremely durable feet, the eight human children had either boots or ice skates covering their feet the entire time they were outside.

 Overall, the kids had a real fun time at the Skelebros' home. And they didn't just play outdoors in the snow the entire time they were there either. After they were done playing in the snow, they went inside the Skelebros' home to do a secret Santa gift exchange and while exchanging presents, they warmed themselves up by the fireplace in the living room, which had two stockings hanging over it (one for Sans and one for Papyrus), and drank some hot chocolate that Papyrus made just for them; after removing their snow attire, of course. No need to track unwanted snow into the living room. And the Skelebros certainly didn't need to tell the four human girls that twice! As soon as Frisk, Chara, Izzy, and Patty entered the house, they took everything off of their feet including their socks. XD They've been jumping at every opportunity to show off their painted toenails lately, since they painted them red and green for Christmas as well as the month of December in general. And nobody blames them because they're painted toes look so cute! X3 And so do the four human boys' Christmas socks! And all thirteen kids' Christmas sweaters (GK's had no sleeves or arm holes)! :D But the four human girls certainly paid the penalty for choosig to roam the Skelebros’ home with bare feet because immediately after the gift exchange, the Skelebros tickled them and the other nine kids all at once for 15 minutes! Just about everywhere on their necks, ears (Asriel, Heather, and Bastian), torsos, arms (everyone except GK), legs, tails (MK and GK), and feet with bones, floating hands, and Gaster blasters! They had to! They made a bet with the kids. If all thirteen of them could beat Sans and Papyrus in a snowball fight, then they could tickle the Skelebros themselves as punishment for losing. All thirteen kids vs the Skelebros? Thirteen against two? Well that didn't sound too difficult and the kids thought that they would beat the Skelebros for sure! But they were wrong! They were very, very wrong! With Papyrus throwing snowballs like Buddy the Elf and Sans using his teleportation powers, the kids didn't stand a chance! XD And as punishment for losing, they got tickled for 15 minutes, which they were all perfectly fine with. Bastian, especially! The little white rabbit boy loves being tickled so much that he literally placed his always bare 3-toed feet right in Papyrus's lap moments before the tickle torture even started! XD The only downside was that the kids didn't get to tickle the Skelebros back. Not to worry though. On the night of December 23, the Skelebros didn't go without any tickles. Their father, Dr. W.D. Gaster made sure of that. ;)

 8:00pm, a few minutes after the kids' parents picked them up and drove them back to their respective homes...

 Sans: Hehehe. Man, those kiddos sure are fun, aren't they, Pap? *asked Sans with a smile*

 Papyrus: Nyeh heh heh! Indeed, brother! *Papyrus agreed* And what an honor it is that they chose our home over everyone else's, even if it was essentially their only choice.

 At this very moment, both Sans and Papyrus are bundled up warm in their special Christmas sweaters, sweatpants, and socks; despite the fact that neither of them can feel coldness. Papyrus currently has on a red sweater with a green Christmas tree on the front side (the tree has multi-color lights and bones hanging on it) and lots of white snowflakes scattered all over the shirt, black pants with a bunch of white snowflakes and bones scattered all over them (the bones have red ribbons on them), and red socks with white snowflakes and bones on them. As for Sans, he has on a blue sweater with snowflakes and bones scattered all over it and also a white silhouette of Santa in his sleigh with his reindeer pulling the sleigh, black pants with bones scattered all over them and "MERRY CHRISTMAS!" written in big white letters on the sides of both legs, and blue and cyan striped socks with a candy cane-like pattern.

 Sans: Heh. Yeah. I mean, who else's home has an outdoor hockey rink AND probably the best hills for sledding?

 Papyrus: Nyeh heh heh! Exactly! Nyeh heh heh!

 Sans: Heheheheheh.

 Papyrus: So, which part of today did you enjoy the most, brother?

 Sans: Heh. Oh, I don't know. The whole day was fun. Playing outside in the snow, that was pretty… COOL. Heheheheheh.

 Papyrus: Nyehehehehe. You know, I'm in such a good mood right now I'm not going to get upset with you for making that pun. In fact, make as many puns as you want, brother!

 Sans: As many puns as I want? Wow, Pap, you're clearly happy about something. What are you so happy about?

 Papyrus: Oh, lots of things. Our home, our family, our friends, and that it's two days before Christmas! Nyeh heh heh!

 Sans: Heheheheh. Ah yes, Christmas, the time of year when joy and laughter is most… PRESENT. Heheheheh.

 Papyrus: Nyeh heh heh! Well, that was most certainly the case when we tickled the kids earlier!

 Sans: Heheheheh. I know, right? All of their combined laughter was music to my "ears." And good thing we won that snowball fight too! I don't think I would've been able to handle being tickled by all thirteen of them. Let alone one of them!

 Papyrus: Nyeh heh heh! I feel the same way, Sans. Even if I can handle it better than you, I feel the way. Nyeh heh heh!

 Then suddenly, Toby (the Annoying Dog), wearing a dark green dog sweater with a reindeer on the back of it and a reindeer antler headband, jumped up next to Papyrus and barked at him. Toby arrived at the Skelebros' home early this morning for no reason other than to see the kids all together and play with them and possibly tickle them after they all went indoors to warm up after playing in the snow, which he did. He was in the house when the Skelebros tickled the kids and he just jumped right in and helped them. Toby loves those kids and they all love him. And while playing outside earlier today, the kids were kind enough to let Toby ride in their sleds with them while they were sledding down the hills. X3

 Toby: *pants* Bark! Bark! Bark! *pants*

 Papyrus: Oh, hello, little dog. I didn't know you were still here. Did you need something?

 After being asked such a question, Toby proceeded to bark four songs to the Skelebros. First, "Jolly Old St. Nicholas," then Here Comes Santa Claus," then "Santa Claus is Comin' To Town," and then "Up On the Housetop." Yes, even Toby gets into the holiday spirit this time of year, barking songs to those willing to listen (and to those not willing to listen XD) and the songs he "sang" to the Skelebros all happened to have one thing in common. They were all songs about Santa Claus himself! "Santa Claus? Why are all of these songs about Santa Claus?" wondered the Skelebros by the time Toby barked a few verses of the third song and they figured out why immediately after Toby finished barking the fourth and final song.

 ???: HO HO HO!! *exclaimed a mysterious figure with a very recognizable voice on the roof of the Skelebros' home, just mere seconds before sliding down the chimney and into the fireplace after extinguishing the fire*

 Sans: Huh? Someone's on our roof?! Who the hell is on our roof at this time of night?

 Papyrus: *excited gasp* Santa? Is it Santa? Oh please be Santa. Please! Nyehehehehehe!! X33

 Once the figure was in plain sight in the fireplace, Papyrus was overjoyed to see that it actually was Santa Claus! Or rather, his father, DR. W.D. GASTER, DRESSED AS SANTA CLAUS! :D Wearing black boots, red pants, black gloves, a Santa coat, a Santa hat, and a fake beard and carrying a big dark red bag, Gaster then stepped out of the fireplace to greet his two sons and although it was completely obvious that Gaster was dressed as Santa, Papyrus appeared to believe that he actually was Santa Claus! XD

 Papyrus: *overly excited gasp* SANTA! OH MY GOD! IT IS YOU! IT IS YOU!

 Gaster: Ho ho ho! Yes, young man! The one and only! Ho ho ho! Merry Christmas!

 Papyrus: Nyeh heh heh! Same to you, Santa! Merry Christmas! Nyeh heh heh!

 Sans: Uh, Pap, you do know that's just Dad in a Santa outfit, right?

 Papyrus: Wha…

 Gaster: What?! No, I'm not anybody's father! *said Gaster jokingly before Papyrus could answer, pretending that he actually is Santa Claus*

 Sans: Yes you are, Dr. Gaster. You're our father, remember?

 Gaster: Dr. Gaster? Who is this Dr. Gaster that you speak of?

 Sans: You. You're Dr. Gaster, you bonehead.

 Gaster: What? No, I don't know who Dr. Gaster is! Who the hell's that?

 Papyrus: *gasp* Santa! How dare you! *exclaimed Papyrus after hearing Gaster say "hell;" since it's not a polite word to say*

 Sans: Heh. Alright, I'll play along. ...So, "Santa Claus…"

 Gaster: Ho ho ho! Now that's more like it! Yes, young man?

 Sans: Why are you here? Don't you normally deliver presents the night before Christmas?

 Gaster: Ho ho ho! Why, yes. As a matter of fact, I do. Your knowledge of Christmas astonishes me, young man. But the present I have for you and your brother on the other hand has to be delivered tonight because "opening" it requires my presence.

 Papyrus: Oh! Is it the karaoke machine I asked for? And you're delivering while we're awake because you want to sing with us? *asked Papyrus excitedly, unable to contain his excitement at the thought of a receiving a karaoke machine for Christmas and “Santa” singing karaoke with him and Sans*

 Gaster: Ho ho ho! Even better! *claimed Gaster with a mischievous smile*

 Papyrus: Even better? W-w-what in the world could possibly be better than a karaoke machine and you singing karaoke with us? *asked Papyrus disappointedly, either because "Santa" didn't get him a karaoke machine or because "Santa" isn't planning to sing karaoke with him*

 Gaster: Ho ho ho! Look inside this bag and see for yourself.

 Papyrus: Okie dokie! *said Papyrus cheerfully, eager to look inside "Santa's" bag without a second thought* Ooh, toy hands! Neato! *he then exclaimed excitedly after seeing what was inside "Santa's" bag* Nyeh… Strange… They all have holes in them like my father's hands… Why is that, Santa?

 Gaster: Ho ho ho! Oh, I don't know. Maybe because... they are your father's hands! *exclaimed Gaster, breaking character and commanding sixteen floating hands to tickle Papyrus practically everywhere on his cheek bones and neck and his armpits, ribs, spine, hips, and knees on the outside of his sweater and pants… and his socked feet too (bony skeleton fingers tickling Papyrus's feet can sometimes elicit giggles from Papyrus* Hehehehehe. Coochie coochie coo, Papyrus. *he teased, smiling mischievously under his fake beard*

 Papyrus: NYEEEEHEHEHEHEHEHEHHEHEHEHHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHE HEHHEHEHEHEHHEHEHEHEHEHHEHEHEHEHHEHEHEHEHEHEHEHHEHEHE!!! *Papyrus hysterically cackled, bony fingers wiggling and squiggling all over several of his most sensitive spots* DAHAHAHAHAD!!! NYEHEHEHEHE!!! DAHAHAHAHAD, NOHOHOHOHO!!! NYEHEHEHEHEHEHE!!! NOHOHOHOHO, DAHAHAHAHAHAD!!! *he pleaded while cackling, revealing to Sans that he knew that Gaster was dressed as Santa this entire time* NYEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHE!!!

 Sans: Huh. So you did know that Dad was dressed as Santa!

 Gaster: Hehehehehehehe. He did indeed. Shame on him for not telling you when you asked him if he knew it was me, am I right?

 Sans: Well, to be fair, you didn't exactly give him a chance to answer.

 Gaster: Hehehehehehe. True. But regardless of that, he still deserves to be tickled. You and him both!

 Sans: Heheheheheheheh… *Sans chuckled, before suddenly realizing…* Wait! What the *bleep* did you just say?! *he then asked worriedly, shuddering at the thought of being tickle tortured into oblivion*

 Gaster: Hehehehehehe. Oh, you heard me.

 Sans: *frightened gasp* You… You... Y-y-you'll never take me alive! *claimed Sans, seconds before trying to make a run for it* Ahhhhhh! What the hell?! WOOOOAAAAAAH!! OOOOOF!!

 Sans tried to run away but thanks to Toby discreetly tying a long strand of silver tinsel garland around his legs, he didn't make it very far. XD

 Gaster: Ho ho ho! Well done, little "reindeer!"

 Sans: Ugh! Damn you, Toby!

 Gaster: Now, Sans, is that any way to speak to a dog? Hmmm? *asked Gaster, kneeling next to Sans and scribbling his own ten fingers all over his ribs on the outside of his sweater, tickling him and causing him to laugh boisterously* Is that any way to speak to a dog? Hehehehehehe.

 Sans: PFFFFFF… MUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHEUHUE!!! NOHOHOHO!!! HAHAHAHAHAHAHAHAHHAHAAHAHAAHHAHAHAHHAHAHAHAHAHAHAHA!!! NOHOHOHO, SIHIHIR, IT'S NOHOHOHOT!!! *answered Sans through his hilariously boisterous laughter, doing absolutely nothing to resist the tickle torture* HAHAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHA!!!

 Gaster: Ho ho ho! That's "Santa" to you! And he's here to tickle you boys as punishment for tickling those thirteen children earlier today! Hehehehehe. Ho ho ho!

 Then suddenly, Gaster, while putting on his Santa Claus act once again, reached underneath Sans's shirt and wiggled his fingers against his spine. The lower vertebrae to be exact and right where Sans is deathly ticklish. ;)

 Sans: *SNNNNOOOOORRRRRT* BWAAAAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHHAHAHA HAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHHAAHHAHAHA!!!! NOHOHOHOHOHO!!!! HAHAHAHHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHA!!!! NOHOHOHO, DOHOHOHON'T!!!! HAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAAHAHAHAHAHAHAHAHAHA!!!! DOHOHOHOHON'T PUNISH US FOHOHOHOR THAHAHAT!!!! *pleaded Sans thorough his even more boisterous laughter* HAHAHHAHAHAHAHAHAHAHAHHAAHHAHAAHAHAHAHHAHAHAHA!!!! *SNORT* MUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUE!!!!

 Papyrus: NYEHEHEEHHEHEHEHEHEHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHHE!!! YEAH, NYEHEHEEHEHE, DOHOHOHON'T PUNISH US!!! NYEHEHEHEHEHEHE!!! WEEHEEHEEHEE WON THAT SNOHOHOHOWBALL FIGHT FAHAHAHAIR AND SQUAHAHAHAHARE!!! *claimed Papyrus through his frantic cackling, floating hands still tickling eight major tickle spots of his* NYEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHE!!! OHOHOH GOHOHOHOD, PLEEHEEHEEASE STOP TICKLING US, DAHAAHAHHAHAD!!! NYEHEHEHHEHEHEHEHEHEHHEHEHEHEHEHEHEEHEHEHHEHEHEHEHHEHEHE!!! OHOHOHOH, NYEHEHEHEHEHE, SOHOHORRY, NYEHEHEHEHEHEHEHEHE, I MEEHEEHEEAN, "SAHAHAHAHANTA!!!" NYEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHEHEHEHHEHEHEHHEHE!!! "SAHAHAHAHAHAHANTA," PLEEHEEHEEASE STOHOHOP TIHIHIHICKLING US!!! *he pleaded, kicking his legs and flailing his arms frantically to try and get his father’s floating hands away from his body* NYEHEHEHEHEHEEHHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHE!!!

 Gaster: Oh, Papyrus, you don't really mean that, do you?

 Papyrus: NYEHEHEHEHHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHHEHEHEHEHE!!! I DOOHOOHOOHOO!!! *lied Papyrus, not entirely minding his current tickle torture, actually* NYEHEHEHEEHHEHEHEHHEHEHEHE!!! OHOHOHOH MY GOHOHOHOD, IT'S SOHOHOHO UNBEHEHEHEHEARABLE!!! *he lied once more* NYEHEHEHEHEHEHHEHEHEHEHEHEHEHHEHEHEHEHHEHEHEHEHEHEHEHEHE!!!

 Gaster: Ho ho ho! Oh please, this is nothing compared to what “Santa” has in store for you boys later! Ho ho ho!

 Gaster continued tickling Sans with his own two hands and Papyrus with sixteen floating hands for the next five minutes. And on eight of their major tickle spots no less! Cheek bones, necks, armpits, ribs, spines, hip bones, knees, and feet! With so many bony fingers wiggling against those particular spots, the Skelebros laughed to seemingly no end. Papyrus "suffered" more than Sans though since floating hands "attacked" all eight spots at once as opposed to just one spot at a time; but not much more. Since Sans is way more ticklish than Papyrus, the number of fingers dancing all over their sensitive bones almost didn't matter. XD

 Papyrus: NYEEHEHEHEHEHEHEHEHEHHEHEEHEHEHEHEHEHEHHEHEHEHEHEHHEHEHE HEHHEHEHEHEHEHEHEEHEHEHEHHEHEHEHEHEHHEHEHEHEHEHHEEHEHEHE!!! CUHUHUHUHURSE YOU, "SAHAHAHAHANTA!!!" NYEHEHEHHEHEHEHHEHEHEHEHEHEHEHEHEHHHEHEHHEHEHEHEHEHEHEHE!!! CUHUHUHURSE YOU!!! NYEHEHEHEHHEHHEHEHEHHEHHEHEHEHEHEHEHEHHEHEHHEHEHEHEHE!!!

 Sans: HAHHAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHA!!!! *SNORT* NOHOHOHOHOOOHOHOHHOOHOHOHOHOHOHOHOHOHHOHOHOHOHO!!!! HAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHHAHAHA!!!! OHOHOHOHOH NOHOHOHOHOHOHO!!!! HAAHHAHAAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHHAHAHAHAHA!!!! *SNORT* *SNORT* *WHEEZE* MUEHUEHUEHUEHUEHEUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUE!!!!

 Five minutes later, Gaster tickled his boys once again. But this time however, the roles were reversed! This time, Gaster tickled Sans with sixteen floating hands and Papyrus with his own two hands. And once again on their cheek bones, necks, armpits, ribs, spines, hip bones, knees, and feet! Sans, being the extremely ticklish skeleton that he is, definitely "suffered" more than Papyrus this time around! Several sets of bony fingers wiggling against eight extremely sensitive parts of his body were just too much. But he didn't laugh so hard that his head popped off though and he had his sweater, long pants, and socks to thank for that; due to every piece of clothing reducing the feeling of bony fingers scribbling against them.

 Sans: PFFFFFFFFF… HAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHHHAHA!!!!! HOHOHOHOLY *BLEEP*!!!!! HAHAHAHAHHAHAHAHAHAHHAHHAHAHAHHAHAHAHAHAHAHAHHAHAAHA!!!!! OHOHOHOH HOHOHOLY *BLEEP*!!!!! *"sang" Sans through his laughter, changing the lyrics of "Oh Holy Night" followed by gibberish for the next couple of verses* HADKFL SLDLD LXKDQ ODOE IFUCRN NDKD KDIDJDJ!!!!! HAHAAHHAHAAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!! HEKDKD JEIDIX JSKSOSS JSJSS KSKD KEKED WKDKD SJSIS FICIR SJEJE!!!!! HAHAHAHAHAHAHAAHHAHAHAHAHAHAHAHHAHAHAHAHHAAHAHAHAHAHA!!!!!

 Gaster: Ho ho ho! That's not how that song goes! *commented Gaster, intentionally rhyming "goes" with "ho ho ho" while tickling eight of Papyrus's tickle spots one by one with his own sets of fingers starting with his socked feet*

 Papyrus: *snickers* Nyeeheeheeheeheeheeheeheehee! Yes! Tickle my feet just like that the entire time, "Santa!" *requested Papyrus, snickering every once in a while as his father tickled his socked feet* Nyeeheeheeheeheeheeheeheeheehee! No need to tickle me anywhere else! *snickers* Nyeeheeheeheeheeheeheeheehee!

 Gaster: Ho ho ho! Not a chance! *exclaimed "Santa," right as he moved his hands up to Papyrus's knees*

 Papyrus: Nyehehehehehehehehehhehehebeheheheehehehhehehehhehehehehehehehehhe!!! *Papyrus immediately cackled, kicking his legs so much that Gaster was forced to hold his legs down with floating hands a few seconds later* Nyoooooohoohoohoohoohoohoohoohoohoohoohoohoo!!! Nyehehehehehehehehehehe!!! Nyoohoohoohoohoo, nohohot thehehehere!!! Nyehehehehhehehehehhehehehehehehehehhehehehehehhehehehehehhehe!!!

 Gaster: Ho ho ho! Yes, there! And here!

 Papyrus: Nyehehhehehehehehehehhehehehehehehehehehehehehehehehehehehehehe!!!! *Papyrus cackled harder once Gaster began kneading his hips*

 Gaster: And here! And here!

 Papyrus: Nyehehehheheheheheheheheheheheheheehehehehehhehehehehehehehe!!!!! *Papyrus cackled even harder once Gaster began wiggling his fingers against his armpits and ribs*

 Gaster: And here! And here!

 Papyrus: NYEEHEHEHHEHEHEHEHEHEEHEHEHEHEHEHEHHEHEHEHEHEHHEHEHEHE!!!! *Papyrus guffawed once Gaster began wiggling his fingers against his neck and cheek bones*

 Gaster: And here as well!

 Papyrus: NYEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEHEEHEEHEEHEEHEEHEEHEEEHEE HEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEE!!!! *Papyrus shrieked, cackled, and laughed at the top of his nonexistent lungs the moment Gaster began wiggling his fingers against his ungodly sensitive spine underneath his Christmas sweater* OOOOWOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOO!!!! OHOHOHOHOHOH MY GOHOHOHOD!!!! NYEHEHEHEHEHEHEHEHEHEHEHEHEHEHEEHHEHEEHEHHEHEHEHEHEHHE!!!! OHOHOHOH MY GOHOHOHOD, LEEHEEHEEAVE MY SPINE ALOHOHOHONE!!!! *he pleaded, wishing that Gaster was tickling him literally anywhere else instead* NYEHEHHEEHEHEHHEHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHE!!!! PLEEHEEHEEHEEASE NOHOHOT MY SPIHIHIHINE!!!! NYEHEHEHEHEHEHHEHEHHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHEHEHE!!!!

 Sans: *SNNNNOOOOORRRRRT* GYEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEEHEE HAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!! OHOHOHOHOHOH GOHOHOHOHOD, PLEEHEEHEEHEEASE MAKE IT STOHOHOHOHOP!!!!! HAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHA!!!!! PLEEHEEHEEHEEHEEASE, I’LL DOOHOOHOO ANYTHING!!!!! HAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHHAHAHA!!!!! AHAHAHHAHANYTHING!!!!! *SNNNNNOOOOORRRRRRT* MUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUHEUEHUEHEUHEUHEUEHUEHUEHUE!!!!!

 Gaster: Ho ho ho! You and your brother are already doing exactly what I want you do, “little boy!” *said Gaster to Sans, grinning like a “psycho” and chuckling along with his sons’ laughter* Hehehehehehehehehehe. Ho ho ho!

 After another five minutes, Gaster rid his sons of their Christmas sweaters for the time being, lifted them up into the air with his telekinesis, and then placed both of them telekinetic holds in "I" positions in midair, rendering them nearly immobile for the next while*

 Sans: Ahhhhhh! Oh no! W-w-what are you going to do now, "Santa?" *asked Sans worriedly, both him and Papyrus struggling to get out of the air and back on the floor*

 Papyrus: Nyeh! And why did you remove our sweaters? How the heck are we supposed to get into the holiday spirit without them? *asked Papyrus, irritated that he and Sans had their sweaters removed against their wills*

 Gaster: Ho ho ho! Why, with a little music of course! *answered Gaster, pulling out four xylophone mallets and handing them to four floating hands he just summoned* Ho ho ho! You hear that, little "reindeer?" *he then asked Toby, cuing him to start doing something cute and funny at the same time*

 Toby: Bark! Bark! Bark!

 Gaster: Ho ho ho! Good "reindeer."

 Uh oh! Music? Xylophone mallets? That can only mean one thing! Gaster wants to tickle his sons by playing their ribs like xylophones while Toby barks Christmas songs! XD And that is exactly what he did with floating hands for the next 30 minutes too! But not just that though; while the floating hands were playing along with Toby's renditions of "Jingle Bells," "Deck the Halls," "Little Drummer Boy," "Joy to the World," "Holly Jolly Christmas," "Carol of the Bells," "We Wish You a Merry Christmas," "12 Days of Christmas," "O' Christmas Tree," “Silver Bells,” and one song from a stop-motion animated film that is considered both a Halloween and a Christmas film, Gaster also tickled his sons just about everywhere on their bony bodies with red and green tickle beams from floating hands, his own two hands, and Gaster blasters with white beards and Santa hats! ;) The Skelebros still had on their pants and socks but those pieces of clothing however did very little to reduce the tickly feelings of the beams on their legs and feet. And the beams tickled like hell too! In fact, they made the Skelebros laugh harder than the xylophone mallets! A lot harder! And unlike fingers, tickle beams are insanely effective against Papyrus's bony feet! Even with socks on! And his and Sans's combined laughter was certainly a magnificent addition to Toby's "lead vocals" and Gaster's "xylophone playing!" Best "backing vocals" ever according to Gaster! XD

 Gaster: Ho ho ho! Yes! Now this is my tempo! Good job, everyone! ...No, wait, my apologies. Not "good job." Perfection! Absolute perfection!

 Sans: *SNORT* HAHAHAHAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHA AHHAHAHAHAHAHAHHAAHHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHA HAHAHHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHHAHAHA HAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHA!!!!! *SNORT* *SNORT* *WHEEZE* MUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUE HUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUE!!!!! *SNORT* *SNORT* *WHEEZE* HAHAHAHHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHA HAHAAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHA!!!!! OH JEEHEEHEEHEEZ, MAHAHAHHAAHAKE IT STOP!!!!! *pleaded Sans through his laughter, having difficulty maintaining his composure, as usual, while being tickled* HAHAHHAHAAHAHAHAHAHAHAHAHAHHAHAHAHAHAAHAHHAHAHAHAHAHAHA!!!!! MAHAHAHAHAHAKE IT STOP!!!!! HAHAHHAHAHAHAHAHHAAHAHHAHA!!!!! PLEEHEEHEEHEEASE MAHAHAHAKE IT STOHOHOHOP!!!!! *SNNNNOOOORRRRT* MUEHUEHUEHUEHUEHUEHUEHUEHUE HUEHUEHUEHUEHUEHUEHUEHUEHUE...

NYEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHE…

 Gaster: Ho ho ho! That it is, my boy! That it is! Ho ho ho!

 After a musical thirty minutes, Gaster vanquished his floating hands and placed his sons on the floor in sitting positions. But the tickles didn't stop there though! After placing his sons on the floor and summoning hands to hold them against the floor, he took two feather dusters, one red and one green, and "dusted" his sons' rib cages and spines, tickling them yet again.

 Sans: AHHHH!!! AHHHHAAHAHAHHAHAHAHAHAHAHAHHAHAHAAHAHHAHAHAAHAHA!!! "SAHAHAHAHANTA," NOHOHOHO!!! HAHAHAAHHAHAHAHAHAHAHAHAHA!!! DOHOHOHON'T YOU THINK WEEHEEHEE'VE "SUHUHUHUFFERED ENOUGH AHAHAHALREHEHEHEADY?!?! *asked Sans in disbelief while Gaster was "dusting his ribs and spine with a green feather duster and Papyrus's ribs and spine with a red feather duster* HAHAHHAHAHAHAHAHAHAHA!!! *SNORT* HEEHEEHEEHEEHEEHEHEEHEHEEHEEHEHEEHEHEEHEEHEEHEEHEHEEHEE!!!

 Roughly three minutes later, Gaster vanquished his hands and let his sons put their sweaters back on. But while they were doing so, Gaster summoned hands to hold their legs against the floor and then with his own two hands, he pulled off their Christmas socks, revealing their bare bony feet.

 Sans: Ahhhhhhhh! Nooooooo! No, not more tickling! *pleaded Sans*

 Papyrus: Nyoo hoo hoo! Please don't use blasters again! *pleaded Papyrus*

 Gaster: Ho ho ho! Just one last thing to do before I let you boys go for real! *said Gaster cheekily, pulling two long feathers, one red and one green, out of his Santa coat* At my "reindeer's" request, I must tickle your feet with these feathers for three minutes! Starting… NOW!

 Sans: PFFFFFFFF… HAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAHAHAHAHAHA!!! *laughed Sans hilariously the moment he felt two feathers saw in between his toes* OHOHOHOHOHO NOHOHOHOHOHO!!! HAHAHAHHAHAHAHAHAHAHA!!! NOHOHOHOHO, NOHOHOT THE FEEHEEHEEHEET!!! HAHAHAHAHAAHAHAHHAHAHAAHHAHAHAHAHAHAHAHHAHAHAHAHAAHAHA!!! STOHOHOHOHOHOP!!! *he pleaded, the two feathers now twiddling against his tarsals* HAHAHAHHAHAAHHAAHAHAHAHAHAHHAHAHAHAHAHAHAHAHAHHAHAHA!!! *SNORT* *SNORT* MUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUE!!!

 Gaster tickled Sans's feet with two feathers for an entire minute. But then after that minute was over, it was Papyrus's turn and boy was he nervous! He was nervous because feathers are utensils that will surely make him laugh; because they're capable of tickling the ligaments that link his tarsals, metatarsals, and phalanges together, spots on his feet that can't be reached with fingers (because fingers are too big to fit in between every bone that makes up the skeleton foot).

 Papyrus: NYEEEEEEEEEEEEEEEEEEEEEEEEEHEEHEHEHEHEHEHEHEHEHEHEHEHHEEHE HEHEHEHHEHEHEEHHEHEHEHEHEHEHHEHEHEHEHEHHEHEHEHEHEHEHEHE!!! *Papyrus shrieked, cackled, and laughed maniacally the moment he felt the plumes of two feathers wriggle in between his foot bones and then wiggle and twiddle against his sensitive ligaments* OHOHOH GOHOHHOHOHOD!!! NYEHEHEHEHHEHEHEHEHEHHEHEHEHEHHHEHEHEHEHEHEHEHEHHEHEHHE!!! OHOHOHOHOHOH MY GOHOHOHOD, GEHEHEHEHET THOHOHOHOSE THINGS AHAHAHHAAHAWAY FROM MY FEEHEEHEEHEEHEEHEEHEET!!! *he pleaded, shaking his feet like crazy only to wind up having them held completely still moments later by floating hands* NYEHEHEHEHHEHEHHEHEHEHEHE!!! OOOOOOWOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOO HOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOOHOO!!! NYEEEEEEEEEHEHEHEHEHEHEHEHEHEHHEHEHEHEHEHEHHEHEHEHEHEHE!!!

 Gaster tickled Papyrus's feet with two feathers for an entire minute. Right on the "death" spots! Then as soon as that minute was up, Gaster finished it all out by tickling Sans's feet with the green feather and Papyrus's feet with the red feather for one whole minute. And once again, he focused entirely on the most sensitive areas of their bony feet. Papyrus, the ligaments and Sans, everywhere else. XD But it wasn't so bad during the last minute, since Sans and Papyrus each only had one feather tickling their feet as opposed to two. ;)

 Papyrus: NYEHEHEHEHHEHEHEHEHEEHEHEEHEHEHEHEHEHEHEHEHEHHEHEHEHEHEEHE HEHEHEHEHHEHEHEHEHEHEHEHEHHE HEHEHEHEHHEHEHEHEHHEHEHHEHE!!! OH PLEEHEEHEEASE TEHEHEHELL ME WE'RE AHAHAHAHAMOHOHOST DOHOHOHONE!!! NYEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHE HEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHE!!!

 Sans: PFFFFFFFF… HAHAHHAHAHAHHAHAHAHAHAHAHAHAAHAAHAHAHHAHAHAHAHAHAHAHHAHAHA HAHAAHAHHAHAHAHAHAHAHAHHAHAHAHAHHAHAAHAHHAHAHAHAHAHAHAHA!!! OHOHOH JEEHEEHEEHEEZ, HAHAHAHAHAHAHAAHHAHAHA, I SUHUHUHURE HOHOHOPE SOHOHOHO!!! *SNORT* *SNORT* MUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUEHUE!!!

 After one more minute of tickling his sons' feet, Gaster released his sons and stopped tickling them entirely. And right as he freed the two younger skeletons themselves, they swiftly put their Christmas socks back on and then Papyrus ran over to the couch where Toby was resting, to give him a talking to for supposedly working with his and Sans's father*

 Papyrus: Ugh! You! Little white dog, how could you! *shouted Papyrus, holding Toby up in front of him and looking him straight in the eye to let him know that he was annoyed with him* We welcome you into our home and you do absolutely nothing to help us?! You could've done more than just bark Christmas songs, you know! Actually, come to think of it, did you "talk" our father into tickling us?!

 Toby: Bark! Bark! Bark! *barked Toby in response, right before inadvertently tickling Papyrus's skull by licking it like any happy dog would*

 Papyrus: Nyehehehehehehehehehehe!!! *laughed Papyrus, Toby’s tongue tickling his skull* Nyoohoohoohoo, nohohohot my face!!! Nyehehehehehehehehehe!!!

 Sans: Awwww! Cut him a break, Pap. It's Christmas.

 Papyrus: Nyeh! Fine! *said Papyrus with an irritated tone in his voice in response, while moving Toby away from his face and setting him back on the couch*

 Gaster: Hehehehehe. Papyrus, Toby didn't "talk" me into anything. Everything I did after sliding down the chimney, that was all me. And I wasn't just getting back at you boys for tickling those children earlier today either. I also did what I did because I thought it would be funny… and fun… like your real present.

 Papyrus: *excited gasp* Present? You… You got me a present? For… For real? Oh my god, where is it? *asked Papyrus excitedly, under high hopes that Gaster is telling the truth this time around*

 Gaster: Hehehehehe. Look in the bag.

 "Look in the bag." Once Papyrus heard Gaster say that, he shuddered at the thought of more floating hands popping out of it to tickle him once more. But what Papyrus saw inside the big red bag instead was a BRAND NEW KARAOKE MACHINE! :D Just what he was hoping for! X3

 Papyrus: *excited gasp* OH MY GOD! THE KARAOKE MACHINE I ASKED FOR! Oh my god, thank you, Dad! Thank you!

 Gaster: Hehehehehe. You're welcome, Papyrus. If anyone here deserves a karaoke machine, it's you. And just so you're aware, I'd be happy to stick around and help you… test it out.

 Papyrus: *excited gasp* Oh my god! Are you… Are you saying you'd like to sing with us?

 Gaster: Hehehehe. I am.

 Sans: Heheheheheh. Well then what are we waiting for? Let's hook it up!

 And with that, the three skeletons spent the rest of the night singing karaoke together and since it was two days before Christmas, they sang nothing but Christmas songs. And at one point during the session, Sans and Papyrus put on elf hats and ears and pretended to be two of Santa's elves since Gaster was dressed as Santa the entire time he sang karaoke with them. Speaking of Gaster, he did offer to remove his Santa outfit before he started singing but decided to leave it on after being told by his sons that he could do so. If someone has access to a Santa outfit during this time of year, it's custom to allow that person/monster to wear said outfit! XD Why, even Toby "sang" some songs with the three skeletons. Not the entire time but when he did, he barked along with the three skeletons as they sang and since he still had on his reindeer antler headband, the three skeletons pretended that he was one of Santa's reindeer; a reindeer with a green Christmas sweater. Overall, singing karaoke was a fun time as a well as a fun reward for the Skelebros for putting up with 45+ minutes of tickle torture and for being amazing hosts to thirteen children earlier today. X3 And after singing karaoke with his sons and  after posing for some family pictures in his Santa outfit alongside his sons dressed as elves (just the hats and ears) and Toby dressed as a reindeer, did Gaster leave his sons' home through their chimney? Yes. Yes, he did. XD And somehow, Toby did too! XD

 Gaster: Ho ho ho! Merry Christmas to all and to all, a good night! *shouted Gaster on the roof of his sons' home, just mere seconds before teleporting Toby and himself back to his (Gaster's) home in the woods*

 THE END.

[sumechiayuu]

which undertale is the most ticklish cuz it actually says a lot about you

Frisk, Chara, and Asriel: THE MOST TICKLISH one touch could have them squealing

Undyne: not now but when she was a kid she was

Papyrus and Sans: no lol

Alphys: slightly

I'm done now lol

[giggleeclown]

Some more undertale brainrot:

Sans loves making other people laugh, but he’s more reserved when it comes to other people hearing his laugh. He tends to snort when he laughs hard enough and he can’t help but be a little bit embarrassed by it. But as he gets to know everyone and becomes closer with them, he starts opening up more, and becomes more involved with the tickle shenanigans that tend to happen around his friend group, especially Toriel and Frisk.

Papyrus loves grappling and play wrestling with Frisks, and it usually leads to him taking on the role of “tickle monster”. He usually lets Frisk get back at him, but he sometimes legitimately loses tickle fights against them because he’s way too ticklish for his own good, lol.

Undyne also takes on the role of “tickle monster” whenever she wrestles with the human. She’s a bit of a sore loser and won’t usually let Frisk win, but if Papyrus is there he’ll team up with Frisk, just to get back at her. He and Undyne sometimes devolve into tickle fighting during training if it’s a day where they aren’t taking it that seriously.

The only person Undyne would ever let win a tickle fight is Alphys, because she’s a good gf and she likes seeing her happy (aww)

I feel like Asgore is kind of neglected by the fandom sometimes, but he really is such a fluffy soft guy! He loves to playfully tickle Frisk along with Toriel, but they sometimes get emotional because it reminds them of their own children the lost (😭) but it makes Frisk so happy having affectionate parental figures (wether they end up back together or not), and they’re pretty quick to adapt more tickling into their day to day life.

THANK YOU FOR INCLUDING ASGORE AND TORIEL

WAAAAAAAAAAAAAAAHHHHH

THESE ARE SOSOSOSOSOSOSOOO FUCKING CUTE NONNIE THANK YOU FOR THESE IM BASKING IN THEM

[ticklishshenanigansau]

Undyne seems to enjoy keeping Papyrus on his toes. She knows he's strong, and she's always is excited to tussle with someone who can take her strength. Sans isn't a fan of how rough she gets with his brother, however....

Some news from Omega

[huds-hub]

“RAWR!!!” The small one pounced at the taller; ticklish attacks in the forms of nibbles to the fish’s neck, sides, and stomach.

Undyne chuckled at the playful nips to her sides and stomach. Everything was fine and dandy until her furry friend got to her neck.

She pulled back and gave an un-warrior-like squeak.

AAAAAWWWKKKWWAAAARRRDDD...

“Oh. My. GOD. You did NOT hear that!”

Looks like someone found this fish’s weak spot.

[kochofairy]

Overwhelming

@rockets-sillyobsession Hiiii you got me again! Here’s your Squealing Santa fic, I hope you enjoy!! I’m sorry it’s late again I tried my best I swear

Thank you @ticklygiggles for hosting!

Fandom: Undertale

A very giggly Alphys hid her blushing face behind her hands. She was in Undyne's bed, with Undyne lying next to her, smirking in amusement.

"Alphys, I'm not even tickling you anymore!" She heard Undyne laugh. "C'mon, look at me!" 

Alphys peeked through her fingers, only to see Undyne's fingers wiggling right over her face. She immediately hid again, giggling even more. 

"Alphyyyys," Undyne teased. "You gotta look at me if you want me to tickle you!"

Alphys loved tickling. This was something she didn't even realize about herself, until discovering the online communities of the surface world. And once she explored those communities, learned about this secret love of her's and eventually told her girlfriend about it, Undyne had made it her duty to indulge her as much as she wanted.

Alphys forced herself to lower her hands and stare at the fingers hovering over her, still giggling and squirming in anticipation.

"Thereee you go," Undyne praised, and she began wiggling a single finger into her bellybutton. Alphys arched her back, falling into squealing laughter and snorting. "Ohoho, there it is! This is just a little snort button huh?"

"Nohoho it's noooot!" Alphys managed to whine between her hysterics.

"Oh?" Undyne reached for and lightly squeezed Alphys' knee. "Right I'm sorry, thiiis is your snort button right?" She yelped, snorting once again as if to answer her question. "Yeahhhh that's it, that's where we get our snorts. Do you like that spot better?"

Alphys was much too flustered, and too overwhelmed to respond at this point. Overcome by her laughter, and by the ticklish feelings, she simply began batting away at Undyne's hand. 

"Hm? You had enough?" She nodded, and Undyne wrapped her arms around her to cuddle as she caught her breath. "You are wayyy too ticklish Alphy." Alphys could only giggle in response, a content smile plastered on her face.

The two stayed like that for a few minutes, though Alphys didn't stay so content for long. The longer she lay cuddled up with Undyne, the more she desired something a little more...as there was more to her little interest than the "ticklee" side of things. So Alphys merely brought her hand to Undyne's side and squeezed.

"No," was Undyne's blunt response.

"Ah, I, uh...sorry," she stammered, immediately withdrawing her hand.

Undyne sighed, and chuckled a bit. "Alright...I'm joking. You can do it."

Alphys lit up, then sat up in the bed. "Um, is it ok if I...?" She gestured at her. Undyne waved her hand in a "go ahead" motion, and Alphys went and sat over hips. Her hands rested timidly on her waist. This wouldn't be the first time Alphys tickled her, but she never failed to get a little nervous about it every time.

"Go ahead hon, it's fine," Undyne reassured her. Alphys gave her a grateful smile, and hesitantly began sliding her hands up her body. When her fingers reached her neck and ears and began gently wiggling, Undyne's lips curved into a wide grin. This was the only area on her that was really sensitive to light touches.

Undyne shifted underneath her, twisting around and pressing her lips together. Alphys began to laugh. "Are you holding it in?"

"Nooooope."

"Are you suuure?"

"YehUP!" She said, clearly suppressing her giggles.

Alphys' hands gradually grew more confident, moving more quickly. Undyne wasn't nearly as ticklish as Alphys was, but that wasn't a problem. Not if you know how to tickle someone. Alphys stayed around her ear fins for a while, causing her laughter to pour out more the longer she went on.

"Okay okahahay, mohohove to a different spohohot!" Alphys' eyes sparkled gleefully, and she shook her head. She was giggling just as hard as Undyne was, watching her struggle. She did eventually switch to digging into her ribs, trying to go for it when she least expected it, and Undyne threw her head back in laughter. "GAHAHAHA DAMMIT!"

Alphys squealed, positively giddy. Her heart was swelling happily from seeing Undyne get this way. She wasn't tickling as hard as she could have been, out of the worry that it might hurt if she was too rough. Not that there was any way she could actually bring harm to the literal warrior beneath her. But the worry stayed with her regardless. 

She ignored that thought, and continued giggling down at her favorite 'lee. "Tickle tickleee!" She chanted.

"DOHOHON'T you freaking 'tickle tickle' mehehehe!"

Alphys gasped in mock offense. "But I wanna 'tickle tickle tickle' you!"

"Youhuhuhuhu dohohohork!" Just for that, Alphys vibrated her fingers into her ribs a little more vigorously.

Alphys kept this up, still laughing along with her. Her excitement was almost overwhelming. For a moment she wondered if even Undyne might've been getting overwhelmed. But no, Undyne was very tough. Even though the idea of pushing her too far was worrying, she could no doubt take more than this.

Of course, she did decide that she had enough at some point. "Okahahay, okahahahahay!!" She finally took Alphys' hands and held them away from her. "Okayokayokay alright. Okay." She closed her eyes and let herself calm her laughter down. When she opened them again and saw Alphys still smiling at her, they both collapsed into more giggles. Undyne pulled her into a hug, letting her lie on top of her.

"Did you like that?" Alphys asked.

"Yeah. That was fun." Undyne scribbled at Alphys' back for a second. "But this is even more fun." She squeaked, whined and giggled into Undyne's chest, blushing a bit. Undyne chuckled at how fast her "tickler" side seemed to vanish.

Alphys loved tickling. And she may have been shy and bashful about it, but she loved that she loved such a sweet, wholesome activity as this. And it made her happy that her girlfriend loved this about her too, and that she could share it with someone she cared about so much.
