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 Disembodied starts. Mortimer also comes through here. When Mortimer appears here, the poster shows his face. Impure Mouse 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 Goofy 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.
