The Coatroom (Cloakroom in PAL regions) is a room in the Gloomy Manor in Luigi's Mansion: Dark Moon. This room can be accessed by going into the bottom-right door of the Foyer. The Coatroom is actually a medium-sized room divided by a wall, creating two separate rooms. The first room has a closet with hanging coats and a toilet with different wallpaper around it. Sitting on the toilet will take the player to the other side of the wall, which is actually a bathroom with a shower and a sink. Removing the carpet and the towel in this room will yield several coins, bills, and gold bars.
During the first mission, Poltergust 5000, Luigi must go to the Coatroom to capture the two Greenies that had stolen the Strobulb from the Poltergust 5000. In the second mission, Gear Up, if Luigi sucks up the carpet on the right side of the room, a Gold Greenie appears. In the third mission, Quiet Please!, if Luigi sucks up all the coats hanging in the closet, a Gold Greenie appears.
In the fourth mission, Visual Tricks, if Luigi enters the room he will need to capture three Greenies.
