129 looks like Chica from Five Nights at Meiko's.
She is straight, very energetic around kids, and loves to cook. She makes herself very kid-friendly when a kid under 11 is around, and otherwise is a quiet girl who spends most of her time in the kitchen. She enjoys singing, her favorite thing to cook is pizza, and she throws pizza slices at you if you make her mad.
When she's in a pickle, she can rely on her brain to create something that will help at least a bit.
As a child, she was neglected by her parents, causing her to be alone until she was 12 years old, when her parents were arrested for child abuse. She was then placed in an orphanage where children were kept in cages and given little food. She escaped at 14 years old, and got a job at Freddy's. The other workers there know very little about her past, and she keeps quiet about it as well. She is used to being alone, so she isn't usually with other people unless asked to be or if she's working.
