The Ballerina Green Room Closet is a bonus room that is unlocked by owning the Ballerina Green Room Closet door. It was the special puzzle piece item during Dark Swan Week 2012. Like other bonus rooms, you cannot apply wallpaper or floors to the room. However, you can decorate it with other items. This room is bigger than the regular rooms in your house. This room can be "hidden" from other players by keeping the Ballerina Green Room Closet door in your inventory. If you add the Ballerina Green Room Closet door to any of your rooms, other players can then view and visit the room.
