Coatroom

The Coatroom is a room in Gloomy Manor in the game Luigi's Mansion: Dark Moon. It can be accessed from the Foyer and inspecting the toilet will take Luigi directly to the Bathroom.

History
During A-1: Poltergust 5000, Luigi heads into the Coatroom to vacuum up the Greenies in the mansion. Luigi manages to get into the Bathroom by using the toilet and finds the Greenies in a shower. The Greenies escape back into the Coatroom where Luigi follows and vacuums them up into the Poltergust 5000.

Luigi can go back into the Coatroom during A-3: Quiet Please! to find and catch a Gold Greenie to earn a lot of money.
