Trivia

 * Though she is the antagonist, she's not exactly allies with Ennard. Both have the same plan of escaping the pizzeria, but go different ways, making them disagree with each other in some cases.
 * When Baby exposes her true colors (at least halfway into the film), it ended up being the biggest plot twist in the Five Nights at Freddy's franchise among audiences.
