William Afton being chased around the Safe Room by the ghosts.

The Safe Room is a secret room within Freddy Fazbear's Pizza. According to both the phone calls and minigames in Five Nights at Freddy's 3, there was a "Safe Room" that was hidden from the cameras and was invisible to animatronics, where employees could put on the Spriinglock suits, and bleed out in if necessary. This room ended up being covered with a false wall, due to the claim of budget restrictions. According to the map of the minigames in between nights in the third game, this room is right next to the Restrooms, near the entrance. It is implied that this is the room the ther Missing Children's Incident occured.
