Lemme just add some curel king headcanons of mine because hell yeah.
1. His actual roblox model he has his tongue sticking out a lil yeah? I'd like to think whenever hes focused on something he sticks out his tongue a bit out of habit, he whenever the player fights the king you kinda just see him doin a lil angry ( >:b ) expression with his eyes narrowed at the player, especially when doing a really precise attack.
2. The king is A damn connoisseur at finding the warmest and fuzzy comfortable cloths for both himself and the citizens, like I'd imagine hes pretty a lil frugal at spending royal clothes he'd probably use the same ones he'd had for a while, all except for like real warm fuzzy capes that, that man just looks like he has a puffy cape collection. (although that dont mean his poor cold freezing ass is ever gonna be warm due to the ice dagger lol)
3. I'd like to think whenever he visits another kingdom for some kind of idk royal meeting or trades or something, but while he's there he'd probably make little kids snow cones, and summon cute snow sculptures to entertain them when he's walking on the way there.
4. Look, if griefer had a name and its brad of all things, i headcanon the cruel kings name is Kingsley because (King)sley... Why? Because funny.
5. The curel in curel king i like to think was because Blackrock had a long line of evil and curel rulers.... So when the king rolled around and was actually nice and running the damn kingdom nicely, most of the new gen citizens deadass thought it was his sir name or something. But the outsiders especially form far away lands probably still believe hes a curel king. and those who aren't quite near but not too far probably thought it was bitter people making propaganda against him, since they keep hearing the king is being a good ruler.
6. Assuming the king has had the ice dagger for a while now he's probably haven't slept good at all, so... Eyebags and tired yawning for days! Yippe.
7. For no particular reason the black rock children citizens call the curel king what their equivalent of santa Claus woud be...why? WHY NOT?
