Bunker

The Bunker is Professor E. Gadd's shelter from the hostile ghosts on the Nintendo 3DS game Luigi's Mansion: Dark Moon.

It is also where E. Gadd pixelates Luigi from the plumber's home, and all mansions in the game. This is apparently the only place where ghosts can't enter. Here, E. Gadd and Luigi can search the Dark Moon pieces, and repair key objects that were broken. It is full of screens and a platform in the floor with a pipe that takes ghosts and money to the Vault. There is also the device E. Gadd uses to clean the Dark Moon pieces.

Trivia

 * The bunker's exterior resembles E. Gadd's original lab in Thwomp Volcano during the events of Mario and Luigi: Partners in Time.
