List of Boos

Boos are undead ghost enemies appear in Luigi's Mansion. During the events, Luigi releases 51 Boos (including King Boo) from the storage room. He must then catch each one throughout the game. 35 of the fifty regular Boos are named and each one always starts out in a particular room (the other 15 form together to make Boolossus). Once Luigi uncovers a Boo, he must drain all of its HP with the Poltergust 3000 to capture it. Boos are capable of fleeing to other rooms, forcing Luigi to chase them down. Some Boos will tackle Luigi when threatened, while others will not. Luigi can still take damage from touching them on contact, however.

The following chart shows each Boo, its amount of HP, whether or not it has the ability to attack, the room it starts out in, and the different hiding places in that room.

Trivia
All Boos' names are clues.
