|Cellar (Luigi's Mansion 2)|
|Normal Ghosts||Grouchy Possessor|
It is the arena of the boss fight with the Grouchy Possessor and the Spider Queen (who he possessed), and is only ever available in the boss mission: "Confront the Source". The one and only time Luigi takes the elevator down to the Cellar, the elevator malfunctions and breaks, preventing further access. The Cellar is made up of one long hallway, and an alcove to the right. As the battle with the Possessor goes on, the Spider Queen will break the walls, allowing Luigi to go deeper into the Cellar. When Luigi defeats the boss, the Spider Queen and her spiders will retreat back into a large crack in the wall.
