List of Boos in Luigi's Mansion: Dark Moon
During the events of Luigi's Mansion: Dark Moon, King Boo uses his power-enhancing crown to give the Boos a new ability: creating Spirit Balls, which makes objects invisible to the naked eye. The player can visit the Boo Canister in E. Gadd's Vault at anytime to see the amount of Boos they have caught.
Excluding Big Boo, only three Boos are required to be caught in the game. These Boos are found in Gloomy Manor's A-4: Visual Tricks, Old Clockworks' C-3: Roundhouse Brawl and Treacherous Mansion's E-2: Double Trouble. Capturing every Boo in a single mansion will unlock an extra mission for that mansion.
This is a list of all the Boos that appear in the game in the order they appear. There are 32 Boos total (not counting King Boo), 22 of which are unique and scattered across the game's missions, and Big Boo counts as ten Boos in E-4: Ambush Manuever. The chart shows each Boo's name, its amount of HP, the mission it is found in, the room it starts out in, and the object or saying that the said Boo is based on.
1 - Due to not having access to the Dark-Light Device initially, these Boos cannot be captured unless the mission is replayed after obtaining the Dark-Light Device in A-4
