Coatroom
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 toiler 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 A-1: Poltergust 5000, Luigi must go to the Coatroom to capture the two Greenies that had stolen the Strobulb from the Poltergust 5000. In A-3: Quiet Please, if Luigi sucks up all the coats hanging in the closet, a Gold Greenie appears. The Coatroom may also be one of the random spider web infested rooms during A-5: Sticky Situation.
