Circus Baby

"'She can dance, she can sing. She's equipped with a built-in helium tank for inflating balloons right at her fingertips. She can take song requests, she can even dispense ice-cream.'-Mr.Afton, Sister Location intro cutscene"Circus Baby is a animatronic built by William Afton. She is the main mascot of Circus Baby's Pizza World and appears throughout the main game.

Role in Sister Location
Although not the first game in the series where she was first introduced, Circus Baby was given a more prominent role in Sister Location. Throughout the main game, Baby guides you with instructions, until the final night. In one night, Baby tells the player about how she was on stage once, counting children in the room. When Afton's daughter was alone, she stopped working until the girl comes closer, with it her storage tank opens out and a claw appear and killed the girl. In the main minigame, we play as Circus Baby feeding cakes to children. In the minigame, Baby has blue eyes, instead of green.
