"Afton's Daughter" (also known as Pigtails Girl) is the minor character in Sister Location. Circus Baby and Original Baby are designed after her. She appears in FNaF 4 and, like her father, William Afton, she has two different appearances.
She only appears in the Death Minigame, in Sister Location, and you can hear her voice at the start of every night(and in the Fake Ending). The only time we see her, she is wearing a pink blouse, a red hairbow, blue skirt and black shoes. She has orange hair and green eyes.
She appears in FNaF 4 briefly, as a ginger haired girl with pigtails and green eyes. She wears an orange shirt, red skirt, and orange shoes. She looks significantly different, but it is believed this is her.
Five Nights at Freddy's 4
In Five Nights at Freddy's 4, her ghost is seen (if approached) teasing the main protagonist (the crying boy) about how the animatronics come to life at night. The protagonist takes this to heart.
Before the events of Sister Location
Chica's Party World/Death
During her birthday party at Circus Baby's Pizza World, she goes against her father's wishes and approaches Circus Baby, who ends up luring her closer using ice cream, and killing her.
In the Minigame, it shows Baby swallowing her with what seems to be a giant claw protruding from her chest, though it could be anything. Ennard (through the voice of Circus Baby) says that, because the kids were screaming and cheering so loudly for the other animatronics, no one could hear her dying.
Five Nights at Freddy's 4 Dialogue
"You'd better watch out. I hear they come to life at night. And if you die, they hide your body and never tell anyone. Why do you look so worried? See you at the party! Ha ha ha!"
