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 a 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.

History
Not much is known about the Gloomy Manor besides that it is abandoned. E. Gadd was using this mansion as a workplace with the Greenies 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.

In-game Description
I, Professor Elvin Gadd, had been studying the ghosts living in this Gloomy Manor, when suddenly the Dark Moon shattered and the ghosts got all hostile-like!
