The Patio is a room in the Gloomy Manor in Luigi's Mansion: Dark Moon. This area is accessed by using the Dark-Light Device to reveal a hidden door near the Library in the Common Hall or by taking the south door in the Kitchen. The Patio is a large, wide-open area. There are several flowers that can be flashed with the Strobulb to drop bills. There is a large fountain in the center with three statues similar to Cheep-Cheeps, one of which is hidden by Spirit Balls. To the right of the fountain is a statue of Professor E. Gadd using a propeller-powered jetpack. Blowing on the propeller either makes the statue release a key or money, depending on the mission. Taking the top left door takes Luigi back to the Common Hall and the north door takes him to the Kitchen. There is a hidden door in the middle of the left wall that takes Luigi under the stairs of the Foyer.
Starting on A-4 and all subsequent missions, the player can shine the shine the Dark-Light Device on the missing statue to have it spit out an amethyst.
