Gloomy Manor

Gloomy Manor is the first mansion Luigi visits in the game Luigi's Mansion: Dark Moon. This mansion is similar to Luigi's Mansion from the first game, and is a standard, run-of-the-mill haunted mansion, in the middle of a storm. It is here that Luigi acquires the Poltergust 5000, the Strobulb, the Dark-Light Device, and the second Dark Moon piece. The sub-boss is the Poltergeist, and the main boss is a giant, purple spider that has been possessed by the Grouchy Possessor, which is located in the Cellar. It has 3 floors and a basement, and features 5 standard missions, a boss mission and a bonus mission which is unlocked after collecting all the Boos in the manor.

Luigi's Mansion: Dark Moon
Not much is known about the Gloomy Manor besides that it is abandoned. E. Gadd was using this mansion to observe the Ghosts before the Dark Moon shattered. During the time E. Gadd spent studying the ghosts he made modifications to the mansion running pipes and wires throughout the mansion. A statue of Professor E. Gadd can be found in the Patio, suggesting that E. Gadd owned the mansion at some point. The music played before the elevator breaks down is the Pause Menu music from Mario Strikers Charged.

Mini Mario & Friends: amiibo Challenge
In Mini Mario & Friends: amiibo Challenge, Gloomy Manor, as well as its surroundings, form the setting of Mini Luigi's stages, contained in a world called Moonlight Mansion. The dilapidated fish fountain at the left of the front yard, along with the polygonal alley, sharp bar fences, and light poles with rough spiraled designs, retrieve their decorative roles around Gloomy Manor.

Trivia

 * This mansion's music played as the background music for the Nintendo 3DS's eShop during Halloween 2014 in North America.
