Deltarune Slumber Party AU

Anyone else remember that Christmas Party Au? Well I thought what if it was a Sleep over, and instead of Sans Au's it's Deltarune characters.

Word count is about a 1,000. This is my first time writing something like this, so feel free to roast me about it. Also I have bad grammar so please excuse any mistakes. And the obligatory there are swears in this.

Swear warning.

"A-Alright everyone, it's time to s-settle down so I can take attendance!" Miss Alphys' request was drowned out by the collective noise of the students on the bus. Whoever wasn't talking amongst their friends was trying to avoid whatever Susie was throwing at them from the back. Susie called it 'pitching practice' for baseball.

"E-Everyone...p-please settle down! We won't be able to leave until I take attendance!"

Kris noticed it seemed to get louder after that. They didn't blame anyone for it; although they themselves felt bad for Miss Alphys, no one really wanted to be here.

The school had a few yearly field trips every year; some good, some bad. Sadly, this was one of the bad ones. Four days at a crummy camp 7 hours away from town. No phones, no TV; just leaky cabins, possible poison ivy outbreaks, and the traditional threat of food poisoning.

But at least it will be a 'great bonding experience' as Toriel put it.

"Maybe you'll even make some new friends."

With who exactly? aside from the other two schools, everyone else on the bus already thinks Kris is 'weird.'

Kris leaned back, reserving themselves to their fate, when a familiar voice shook them from their thoughts. That, and a familiar punch in the arm.

"Hey, Kris. Are you coming or not?" Susie leaned over and whispered.

Kris looked back at their friend, Susie had her bag slung over her shoulder, she kept glancing between Kris and the front of the bus. Miss Alphys was beginning to take role and permission slips amongst the chaos. Temmie threw an apple core at Susie, which was caught and promptly thrown at Berdly's head.

"Com' on ya nerd, ya think I'm gonna go on this lame ass field trip? Hell no! Let's sneak off before Miss Alphys gets to us!"

[ Would you like to follow Susie off the bus?]

Yes No

"Dude, are you coming or not?" Susie was already halfway out the back door of the bus.

[You quickly grab your bag and follow Susie off of the bus. No one seems to notice you]

Susie ran back behind the school, Kris in tow behind her.

"Come on, Kris! I left a window open in the science lab!" Sure enough, Susie had left her textbook propping up a window, "Freaks first."

The lab was empty, save for the classroom essentials and the class pets. Affectionately named 'Pinky' and 'The Brain,' the albino rats. Every now and then they try to open their cage door to look for something. Maybe someday they will find it.

"Doors unlocked, can you grab me some chalk? We gotta hurry before anyone sees us." Susie dropped some cheese into the rat's food dish, Kris opened the teachers desk drawer.

[You found, Box of Chalk, it tastes chalky]

"Oi, do NOT eat that, I call dibs." Susie pointed at Kris, "That's the expensive kind. Gourmet shit."

The two made their way out of the classroom and ran down the hall, making their way to the storage closet.

[ You ask Susie what exactly she has planned.]

"Ain't it obvious?" Susie nodded towards the closet door, "Come on, dude, we both know we would rather be 'solving' Rouxles puzzles than on that shitty field trip. We're only going on it because every other teacher, besides Miss Alphys, is out at a conference for the weekend.

That part was true, hell, that was the only reason that Toriel made Kris go on the trip this year. She wouldn't let Kris stay with Asgore over the break.

Susie continued, "I figured we could just sneak away, say we felt sick and stayed at my place or your dad's place. Meanwhile...we could chill out with Ralsei and Lancer at the palace! Remember, he said we could back anytime. AND WE HAVE OUR OWN ROOMS!"

The plan could work...except...Asgore wasn't at the flower shop right now. He was also out at a gardening convention a few cities over.

But, Toriel didn't need to know that...right?

Susie looked back at Kris and placed a hand on their shoulder, "Listen dude, you don't gotta do this is ya don't want to. I don't wanna get you into trouble with your mom or anything. Mine couldn't care less what I do, but I know Toriel worries easily."

Susie rubbed the back of her neck and waited for Kris to answer.

[You tell Susie it'll be fine, you just have a few phone calls to make.]

"That's great, dude! I'll leave ya to it, I'm gonna go look for more chalk. Lancer really wants to try some."

Kris came back a few minuets later. Toriel sounded worried, and Kris felt a little guilty about lying to her, but this was an emergency. She said it would be fine to stay back in town with Susie. Asgore said Kris can sleep at the flower shop if they aren't feeling well, Asgore always leaves a set of spare keys under the rug for the back door of the shop. Just in case of an emergency. Luckily, there has never been a real need to use them. As for the permission slip...Kris crumpled up the piece of paper and tucked it into their pocket. Susie arrived not too long after Kris had.

"Ready, Kris? I wonder how Lancer and Ralsei have been doing since the last time we came for a visit. I bet they're really bored!" Susie laughed, "Alright, lets go-"

"Susie? Kris?"

Kris and Susie froze in place and slowly turned around. Thankfully it wasn't a teacher, it was just Noelle and Berdly.

"Oh thank god, it's just you two." Susie breathed a sigh of relief.

"I know you two tend to get lost easily, but even a fool can tell this isn't the school bus." Berdly pointed out.

Noelle adjusted the strap of her backpack on her shoulder, "What are the two of you doing in here?"

"Oh, um...well...Kris help me out here!" Susie nudged Kris with her foot.

Running away Robbery

What are YOU doing here?

[You ask Noelle and Berdly why THEY are here as well.]

"Yeah, why ARE you two here?" Susie questioned.

(End of part 1)

Well I hoped ya'll like the first part. It was longer than I thought so I'm gonna upload the next part later on.

Deltarune Slumber Party Au Part 2

Happy New Years Eve everyone! I decided to get this one posted before the year was over. Sorry it's late, school kept me busy.

Anyways, I hope you all enjoy this!

Summary: In order to avoid a god awful field trip, Susie and Kris sneak off of the bus and into the school so they can spend there time in the Dark World with their friends. However, they are discovered by Noelle and Berdly, but why are they here?

Word count 1252-ish and CW for swear words.

[You ask Noelle and Berdly what THEY are doing here]

"Yeah, what ARE you two doing here?" Susie questioned.

10 Minutes Prior

"And that, Noelle, is why the original Dark Souls will always be better than Dark Souls 2. However; if we look at the Diablo Series- OW!" Berdly rubbed the back of his head, someone had thrown an apple core at him. Berdly spun around, but couldn't find who had done it. "Neanderthals, all of them."

Noelle stifled her chuckle. It wasn't polite to laugh, but it was still funny.

I have an idea of who did it, she thought.

Noelle looked back at Susie, who was punching Kris in the arm. They seemed to be talking about something, but Noelle couldn't hear over everyone in the bus.

What are those idiots doing back there?" Berdly asked aloud.

"I dunno, looks like they're just playing to me," Noelle replied.

"I bet they're scheming something..." Noelle could only guess what Berdly was imagining, "They might be planning to run away from the field trip, or maybe even... ROB THE BANK!"

Noelle rolled her eyes, "Come on, don't be dumb."

"You're right, Officer Undyne would never let something like that happen."

"And..this town doesn't even HAVE a bank..."

Besides, aren't you afraid of her? Noelle kept that thought to herself.

Miss Alphys stood at the front of the bus and took the microphone from the driver, "E-excuse me," The feedback from the mic nearly defended Noelle. The bus was finally quiet. "Th-than you. Now I am going to go around and take everyone's attendance A-AND permission forms. P-please have them ready by the time I get to your seats, and...please don't trip me this time."

As Miss Alphys began her descent down the aisle the rambunctious noise picked up again. Noelle looked back to try and get Kris and Susie's attention. They would get into trouble if they were caught roughhousing on the bus.

but they were gone.

In fact, Noelle was only able to catch a glimpse of Kris's hair as the two ran out the back door of the bus. The door shutting quietly behind them.

"What the-"

"What's wrong?" Berdly asked.

"Susie and Kris just left." Noelle answered.

"Huh?" Berdly turned towards the back of the bus and shook his head.

Berdly kicked his feet up onto the seat in front of him, accidentally kicking Catti in the back of the head. "I don't see why that is such a bad thing, Noelle. We'll probably have a better time without them here."

"But they could get into trouble, I don't think-"

"Do what you want, Noelle, I'm not going to stop you...Berdly interrupted.

Noelle stared at her friend for a moment before gathering her things. Glancing up the aisle to see Miss Alphys stopped a little ways ahead of them, trying to calm down Temmie, who apparently lost egg. As quietly as she could, Noelle made her way to the back of the bus and snuck off.

"-It's not our responsibility to take care of a couple or C students anyways. Now, where was I- Hey, wait!" Berdly scrambled to gather his things, grumbling as he did so. "Oh at least let me finish my train of thought!"

Present

"We're just here to get you two back on the bus before Miss Alphys catches you," Noelle answered.

"Technically, we could all get into trouble because of the two of you." Berdly stated.

"Dude, you really could've just stayed on the bus and ignored us. Why did you come anyway? Can you not handle being alone for 5 minuets?" Susie replied.

"I-I only came to take Noelle back to the bus, she's the one who wanted to help you two!"

"Whatever, Nerdly." Susie flicked Berdly's glasses off center.

Noelle sighed, "Come on everyone, lets go back to the bus-"

"Hello...is anybody here?" Miss Alphy's voice echoed throughout the halls. " I-I definitely heard someone. There s-should be absolutely no students in the school a-at this time."

"Shit." Susie whispered. "Quick, into the closet!"

Kris looked between Susie, Noelle, and Berdly.

"Oh no, we're gonna get into trouble. Kris, what do we-KRIS."

[You give Noelle and Berdly a peace sign before ducking into the closet.]

"K-Kris!"

"Noelle, Berdly, are you two in here?" Miss Alphys asked.

"Crap, we need to get out of here. Noelle, I think we should- NOELLE!?"

Noelle peaked out from behind the closet door, "Th-there is a lot of space in here." She laughed weakly.

"What the..get out of there, I'm sure Miss Alphys will understand that we only came in here to bring those idiots back out to the bus."

"Maybe the kids aren't in here after all, I don't remember getting their permission forms."

Berdly walked over to Noelle, "See, she doesn't even know if we are supposed to be on the bus. Lets just sneak back on and-"

"M-maybe someone snuck inside of the school to vandalize it! I-I should go call Officer U-Undyne!"

...

Berdly pushed Noelle into the closet, "Let's see just how big that closet really is. Move it, MOVE IT!"

"Hold on, Berdly!"

The two hit the floor of the closet, taking Kris and Susie with them. The door closed shut behind them.

"SORRY!"

"Shit, Berdly, move your leg!"

[You tell Susie that is YOUR leg]

"Shit, my bad."

Susie helped Noelle sit up, Noelle helped Berdly up. Kris decided to lay down on the miscellaneous papers.

"Why are there so many papers on the floor...and can someone please turn the lights on? I can't see anything." Berdly complained, wiping the dust off of his shirt.

[You tell Berdly he can, if he can find the light switch.]

"Wow, the supply closet is bigger than I remember being." Noelle said.

"Yeah, pretty cozy." Susie sat down next to Kris.

"So...Now would you two like to come back to the bus?" Noelle asked.

"Hell no. Did you hear Alphys? She doesn't even know if we're supposed to be on the field trip. I bet she thinks we're staying home. Bus has probably already left by now." Susie replied.

"So, what do we do now?"

[wait.]

"Huh?"

"Well, Kris and I are gonna stay here. I guess you guys can head out and do whatever you want. We're just gonna sit here and wait." Susie scratched the back of her head.

Berdly tried to open the door, weakly attempting to push it open, "Ha ha, trust me, we are trying to do just that." Berdly threw himself at the door, only to stumble and land beak first into the hard metal. "What the-"

"But, what if we...uhm...wanted to come with you guys..."It came out more like a question than a statement. Noelle sat down next to Kris and Susie.

"Uh...guys." Berdly said.

[You tell Noelle that is a bad idea.]

"Guys."

"And why would that be? You guys are just sitting here." Noelle asked.

"Is the floor shaking or am I crazy?" Berdly shook Noelle's shoulder, but she ignored him.

"No, Kris is right. You guys would just be so bored here with us, you guys should just-"

"GUYS!" WHAT, BERDLY!?"

"Why is the floor shaking!"

Suddenly the floor began violently shaking. Noelle leaned against the wall attempting to steady herself. Berdly fell against the closet door.

"FINALLY, TOOK LONG ENOUGH!" Susie shouted.

Without warning the floor collapsed, Noelle screamed as the four were swallowed by the ebony abyss below them.

Sorry about the ending feeling rushed, but I was struggling to find a way to write it. If ya'll have any advice, I would appreciate it.

Anyway, I hope ya'll enjoyed it and have a fun/safe New Years Eve!
