Their restaurant's concept was to create a special place for children's birthday parties. While mostly serving pizza and cake, the thing that made this restaurant chain special was their "animatronic" wait staff and entertainment. Originally, they were unable to create animatronics. So, instead, they crafted two spring-lock suits that they or their staff could wear to appear as animatronics or place on a stage to perform. Their names were Springbonnie and Fredbear. The concept for the business did so well that they ended up creating a second location: Freddy Fazbear's Pizza. Within this new location, four new animatronics were created and adored. They were Freddy, Bonnie, Chica, and Foxy. William Afton would use his success and the spring-lock suits to act on his cruel and abusive thoughts toward the children who flocked to his restaurant, specifically the five children at the birthday party that he murdered after luring them into the backrooms with the spring-lock Bonnie suit
