Animatronics who go here
Toy Chica (in the rare chance she does appear in here) will appear kind of crouching right beside the paper plate dolls. Withered Chica will appear here with her hands raised blocking ever paper plate doll. Toy Bonnie will appear here staring at the camara so you can't so the room.
