Hydro Generator

The Hydro Generator is room in Haunted Towers in the game Luigi's Mansion: Dark Moon. As stated by Professor E. Gadd, the Hydro Generator is the main source of power of Haunted Towers powered mainly by water. The Hydro Generator is accessed from the Courtyard.

History
During B-1: A Job for a Plumber, E. Gadd sends Luigi to Haunted Towers to fix the plumbing. As Luigi enters the Hydro Generator, a Slammer is seen and it flys upstairs. It appears that the Slammer actually broke the main generator forcing Luigi to head upstairs to the Water Supply for repairs.

During this mission, Luigi can use the Dark-Light Device to reveal a hidden washer and capture MamBoo.

During B-5: Doggone Key, Luigi must chase after the Polterpup through this room.
