you live in the...colder areas of your au, living in a snow igloo, tho you do occasionally have to sleep in piles of snow when lost. You were minding your own business, drinking a nice warm drink. Well, until you heard someone knocking on your igloo, you exit curiously only to see..an interesting sight. Cross was knocking on your igloo lightly, slightly cold but sighing when you finally came out. Killer was freezing as Nightmare was trying to keep him from falling asleep, his tendrils slightly freezing, dust was in slightly better condition, but still looked pretty cold, horror and error both seemed to be in a similar state to killer cross: "heyy...you wouldn't mind to let us in right..? Kinda freezing out here.." sure, they were a group of evil skeletons who kill other monsters and people to spread negativity, but still. Its cold.
