Poltergeist

"Those brainy Poltergeists sure are strong, but they don't seem to be in charge of the other ghosts. I reckon they're still worth studying, though!"

- Professor E. Gadd

Poltergeists (called Boffins in the British English versions) are a type of ghost in Luigi's Mansion: Dark Moon. They are orange and possess large brains. While Luigi explores the Gloomy Manor, Professor E. Gadd insists he captures this ghost for research. An Ancient Poltergeist is the mini-boss of Old Clockworks, and a Strong Poltergeist is the mini-boss of Treacherous Mansion. Poltergeists also appear in the bonus mission in Gloomy Manor and the Old Clockworks. A large Poltergeist called The Brain is the final boss for the co-op mode, ScareScraper.

Abilities
The Poltergeist has the power to move objects with telekinesis. When Luigi fights the Poltergeist, it throws books at him while he searches for it. It can even throw books at Luigi while it is being sucked into the Poltergust 5000 to get away. When the Strobulb is used on it while it is carrying a book, it blocks the light using the book, and so the player must wait until the book is thrown to stun it. It is almost always invisible, but the player can use the Dark-Light Device to reveal its current location and stun it afterward. It also plays the piano during the entire battle. In the Old Clockworks bonus mission, instead of books, it throws the bricks placed around the room.

 * Poltergeist: These big-headed know-it-alls have swollen brains (and egos) that afford them telekinetic power. Sadly, their sense of humor seems to be underdeveloped.
 * Boffins: These big-headed know-it-alls have swollen brains (and egos) that afford them telekinetic power. Sadly, this seems to come at the cost of a sense of humour.

Trivia
