The Lab

The Lab is a room in Luigi's Mansion. It is here that Professor E. Gadd first converses with Luigi. At the beginning of each saved game, E. Gadd will ask the player where they want to go, to the Mansion, the Training Room, the Gallery, or, once the game is beaten, the Hidden Mansion.

Trivia

 * If the player looks in this room closely or uses the Game Boy Horror in the Training Room or the Gallery, they will notice that there is a wooden ladder visible, giving the impression that E. Gadd's headquarters is underground.
