The Red Door leads to a large room with pink and blue wallpaper. The room is filled with toys, clothes and other objects that are meant for the use of children.
The room later turns dark and is filled with the dead corpses of Parker Crane's victims with sheets covering the bodies and rocking horses covered in cobwebs.
When Elise and Carl enter the room, they find Parker's mother abusing him so that he may understand that he is female. Once seeing them, Parker's mother screams and slams the door shut.
