Animal Animatronic: Dinosaur
Name: Dolly the Dinosaur
Nickname: Dolly
During the day: She makes balloon animals and hands them out to kids. Most people don't know this, but she'll often choose the animal based on the kid's personality.
During the night: She is never the first animatronic to leave backstage. Once one of the others leaves, she tends to wander around the kitchen and periodically check on the guards. Sometimes she'll get distracted and follow one of the other animatronics, which means she checks on the guard either more or less depending on who she's following.
As a child
Name: Chloe Sanchez
Age: 6
Appearance: She is small and dark-skinned, with dark brown hair that reaches her chin. She doesn't like brushing her hair, so it's often a huge mess. She likes to wear dresses, which her mother doesn't approve of since she always gets mud on them.
Personality: Chloe enjoys capturing insects and keeping them in little containers - she has a whole collection in her room. She loves drawing, especially animals since she is fascinated by them. It's one of the reasons she enjoys going to Freddy's, since the animatronics are based on animals. She is very friendly, although she doesn't have a lot of friends since people tend to consider her weird. (She isn't completely friendless, though.)
Death: One day while visiting Freddy's, there was a mysterious blackout and Chloe's parents lost track of her in their panic. They couldn't find her again, and after investigating, the police marked her as "missing".
Is there anything else I should add? I tried to make her death fit in with what's happening in the roleplay.
