After the closing of the second establishment and Afton's growing interest in capturing children, William created another sister location, based on his new animatronic, Circus Baby. This location, Circus Baby's Pizza World, was only owned by Afton but served the same basic concept. Circus Baby was made specifically to draw children to her by acting child-like. She could blow up helium balloons, dispense ice cream, and use her claw to grab children and stuff them inside of her.
Circus Baby was specifically designed for trapping and killing children when she was alone with them in a one-on-one situation. Despite being a despicable man, Afton had a family-two sons and a daughter. He actively kept his children away from animatronics, such as Circus Baby, to keep them safe. However, Circus Baby's design was too entrancing to his youngest, Elizabeth, and she was consumed by the animatronic. Circus Baby became aware of the soul of Elizabeth inside her. After losing his daughter to his creation, he shut down the sister location immediately.
