Animatronics Ltd. User Manual 17

Finally after so long, some more FNAF User Manuals from the backstage area. This one details costume removal/replacement. It would also explain why Bonnie in FNAF 2 has half a face. Those pesky screws in the back of the head got rusted in and the heads stripped so the only way to remove his mask would have been to cut it off to get at the eyes to upgrade them and the CPU. I guess they planned to remove the face, get Bonnie ready for opening day, then eventually perform a full over haul along with the other robots afterward. But the robots being so damaged and ugly, the company bought the Toy robots out of necessity for time.
