Character Prep 1, also known as CAM 3, is a location of the game Five Nights at Treasure Island. It seems to be a backstage for mascots. This is where Photo-Negative Mickey and Disembodied start. Suicide Mouse also comes through here. When Suicide Mouse appears here, the poster shows his face. Photo-Negative Minnie also appears here hanging from the ceiling, as seen in TGsEE. Character Prep 1 has two mannequins in both corners of the room. There is a crack in the wall and a poster of a Acephalous costume. There is also a Mickey Mouse badge on the floor. There are multiple wires hanging down across the ceiling. There are also some shirts behind the mascot costume rack.
