Under the Stairs

Under the Stairs is a secret room in Gloomy Manor in Luigi's Mansion: Dark Moon. To access it, Luigi must use the Dark Light in the middle left of the Patio. There is nothing really noticeable about this room, except that it has three Gold Spiders. The room is called Under the Stairs because it is literally under the stairs of the Foyer. There are two doors in Under the Stairs, one that leads back to the patio, and one that leads to the foyer, allowing Luigi to get an Amethyst.
