The Hydro Generator is a room inside of the Haunted Towers in Luigi's Mansion: Dark Moon.
Description[]
The Hydro Generator is a large room that contains a water-powered generator in the center, which serves as the source for all of the water-based power/electricity within the towers. There are bridges that connect on either side of the generator, with streams of water flowing through from the wheels of the generator. There is a barrel located on the bottom west corner, and to the east corner, there is a chester drawer, a treasure chest and another barrel. This room has two doors on the west side; the west door leads to the Courtyard, and the north door leads to the East Hall.
Dark Moon Quest[]
In "A Job for a Plumber," a Slammer can be seen trying to fix the hydro generator in the room, before angrily fleeing upon noticing Luigi's arrival. E. Gadd calls Luigi on the Dual Scream and informs him to inspect the Water Supply to get the hydro generator operating again. If Luigi uses the Dark-Light Device on the invisible treasure chest and opens it, the mission's Boo, MamBoo. After Luigi activates the machine on the Water Supply, the hydro generator gets powered up with water.
In "The Pinwheel Gate," Luigi needs to come here to activate the door to the East Hall in order to access the rest of the eastern tower to chase the Hiders that stole the pinwheel vanes.
In "Graveyard Shift," a Gold Greenie is seen playing in the water.
In "Pool Party," the Hydro Generator and most of the rooms in the eastern tower are rendered inaccessible throughout the mission.
In "Doggone Key," the Hydro Generator is one of the rooms that the Polterpup escapes through.
In "Hostile Intrusion," the Hydro Generator may be one of the rooms infested with ghosts. If it has been selected, then Luigi will fight a few Greenies and Slammers.
