Before the core game play begins, a prologue cut scene is presented to the player, where an interviewer is questioning William Afton, supposedly the creator of the game's animatronic characters, on certain design choices he has made when building the animatronics. William lists several features of Circus Baby, such as her ability to make ice cream, inflate balloons at her fingertips, and take song requests and dance to them. The interviewer is unsatisfied with this answer, as the features William mentioned were not what he was referring to.
