- Nightmare Chica has ADHD
- Nightmare Chica and Sun get along pretty well, tho they don't get time to talk a lot. Since Nightmare also talks a lot of shit about Sun, and since Chica has no filter, she is very blunt towards Sun and the stuff Nightmare says about him, which does strain their friendship a slight bit, but since most of the stuff she says is stuff Sun already knows tho, he doesn't get too fazed about it
- Nightmare Chica once was given a light switch that Bonnie ripped out of a wall upstairs for her to fidget with. Bonnie didn't realize that Chica was fascinated in the light itself and not the light switch but Chica still thanked him regardless.
