They’re a group of 4 skeleton Bitties that were abandoned and horribly abused in their old homes until they found each other on the streets, and they’ve been together ever since. They all have separation anxiety and can not handle being away from even one of them in worry they’ll get hurt. However, they like to cuddle you. Aka when you wake up Nightmare is practically hugging you with his big size, Horror and Dust are cuddling in the crook of your neck, and Killer is on your chest dead asleep.
