The investigation into the child's death ruined Fredbear's Diner. No one wanted to eat somewhere that a child had died, especially not with a case that was still open. The affair was too tragic and too embarrassing for anyone to want to come back, even after Mr. Wendell had repaired Fredbear. Wendell had to put Fredbear's Diner on the market. Eventually, Wendell was contacted by an up-and-coming entertainment business that branded itself as 'Faz Entertainment.' Try as hard as he might, Wendell couldn't avoid being fleeced by Faz Entertainment, who bought the rights to Fredbear's Diner and everything in it for almost nothing. This included the rights to the Fredbear animatronic, the store uniforms, and the name of the store. One of the executives, Frank Faz decided to capitalize on the Fredbear animatronic, rebranding it 'Freddy Fazbear', and making it the new mascot of a chain of children's pizzerias, 'Freddy Fazbear's Pizza'. The idea was to make a profit by making the cheapest pizza possible, drawing customers in (little, bratty, screaming kids that would beg and pester their parents to take them) with the charm of the Freddy Fazbear animatronic, who would interact with the children as it did before in Fredbear's Diner. Frank loved the thing; it was an incredible business measure. Along with Freddy, Frank had gotten an old puppet that had come with the store for free. Frank considered wiring it with animatronic parts to act as Freddy's sidekick, but decided that the thing wouldn't really fit with Freddy's cute animal design, and ended up stowing it in the backroom of one of the new stores. However, the puppet had given Frank and the other executives at Fazbear Entertainment and idea; if one animal animatronic could bring in customers to eat at a kid's restaurant, perhaps another one would bring in more. Really, as long as the kids were entertained, they wouldn't care what they were eating. So, Fazbear Entertainment had their design team put their heads together and come up with a new character; Bonnie the Bunny, a bunny that would play guitar to accompany Freddy's vocals in songs. With a new character accompanying Freddy performing on stage and interacting with kids in the store, profits skyrocketed, and Fazbear Entertainment slowly decreased the amount of real cheese that they put in their pizza.
Initially, in order to avoid similar meltdowns to what had occurred to the original Fredbear, Fazbear Entertainment scrapped the animatronic in favor of a new animatronic design, the "springlock" suits. The initial idea was that it would be more reliable and cheaper to use store employees wearing suits than it would be to purchase additional parts for animatronic endoskeletons, though the Springlock suits were designed to allow operation both through the use of an employee operator or an endoskeleton. However, after learning of an unfortunate incident involving multiple and simultaneous springlock failures at one of the Fazbear locations, in which an employee in a Springlock Freddy suit laughed at a joke, releasing moisture onto springlocks, triggering them to snap shut and disembowel the employee, which caused another employee to shout out in alarm, likewise triggering a springlock failure, the company deemed the suits temporarily unfit for employees, and switched back to endoskeleton operation.
However, the executives weren't satisfied. The addition of Bonnie had been a resounding success, but why stop there? Why not add another animatronic? The design team soon came out with Chica the Chicken. The team gave Chica some additional features, including a "Let's Eat!" bib and a cupcake with eyes designed to incite the kids to eat more cake. However, Chica's addition required some minor design adjustments to be made to Freddy and Bonnie, who shared a golden color design that had been carried over from the original restaurant. From now on, only Chica would possess a yellow coloration, Bonnie would be purple, and Freddy would be brown, though in certain stores a rare "Golden Freddy" could still be seen. But really, why stop there? The design team felt that the band was more-or-less complete, but the performance could use a sideshow. The character would have to be distinctive enough to carry a show on its own, so after the team had decided on a fox character, they put a list of names of whatever was popular at the time in a hat. They pulled out 'pirate', and Foxy the Pirate Fox was born. The new additions were a resounding success, and the pizza deteriorated to something resembling paste spread out on cardboard. It didn't matter. Kids didn't care what they were eating, as long as it was pizza, and they got to laugh and cheer at the animatronics in the new Freddy's Fazbear's Pizza.
