Fazbear Entertainment opens up a restaurant called Fredbear's Family Diner. There was a murder of a child there, so they shut it down. They open up the first Freddy Fazbear's Pizza, where they have costumes of Golden Freddy and Golden Bonny which double as animatronics that sense where the children are and walk towards that area. One day in a sister restaurant, the costumes’ springs fail on multiple costumes, and the Freddy, Bonnie, Chica, and Foxy suits are brought in, while the Golden Freddy and Bonnie suits are taken to get examined. There is a room in the building with no cameras and the animatronics cannot enter. The murderer takes advantage of the Golden Bonnie suit and the room and leads the children into the safe room, and kills them, then stuffs them into the five suits. After this happened, the safe rooms are closed with no explanation. "Nothing is being removed and this room cannot be told about to anyone." After these events, the first child, now the Puppet, decided to put the souls of the dead children into the Foxy, Bonnie, Chica, Freddy, and Golden Freddy suits.
They decide to open a new restaurant, a bigger and better Freddy Fazbear's Pizza. They brought in new animatronics with facial recognition tied to a criminal database to track down the murderer and are allowed to walk around during the day while the old, haunted animatronics are left to rot in a spare parts room, with "an awful smell." The day guard tampered with the electronics using the Golden Bonnie suit to not be suspicious to the animatronics walking around, causing The New Freddy Fazbear's Pizza to shut down. Sometime while the animatronics were changed, the Bite of '87 happened, where one of the animatronics bit one of the guests, leaving him/her without a frontal lobe.Fazbear Entertainment AGAIN decides to open a third Freddy Fazbear's Pizza. They decide to use Freddy, Bonnie, Foxy, and Chica design from the first Freddy Fazbear's Pizza, and not allow them to walk around during the day. On the fourth night of working here, the man who has been instructing you dies because of the animatronics. The murderer lures the animatronics into the safe room, which they cannot enter and destroys them. After this happens, the ghosts of the children trick the murderer into the Golden Bonnie suit, where the spring lock on it kills him.
Thirty years later, a kid wants to open "Fazbear's Fright: The Horror Attraction," using genuine pieces from the original "Freddy Fazbear's Pizza(s)" where, unknown to him, the Golden Bonnie suit still has the soul of the murderer still trapped inside of it. Seeking to get revenge on the children who put him in the suit, he goes to wherever he hears a child's laugh. "Fazbear's Fright: The Horror Attraction" is then burned to the ground through unknown circumstances.
