Poltergeist

Poltergeists (called Boffins in the PAL versions) are mini-bosses in Luigi's Mansion: Dark Moon. They are orange and possess large brains. While Luigi explores the Gloomy Manor, Professor E. Gadd insists he capture this ghost for study purposes. An Ancient Poltergeist is the mini-boss of Old Clockworks, and a Strong Poltergeist is the mini-boss of Treacherous Mansion. It also appears in the bonus mission in Old Clockworks. The Brain, the final boss encounterd in the ScareScraper is the same as the regular Poltergeist except it has 300 HP, or more depending on number of players and difficulty, and is much larger than normal.

Poltergeist 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. It also plays the piano during the entire battle.

The Brain Abilities
In the ScareScraper, it is capable of causing a large explosion to get rid of any Luigis that are capturing it. However, this can be avoided by jumping with the B button (while the suction is still focused on it). It also exhibits all other abilities that a normal Poltergeist has.

Ghost Container Description

 * Poltergeist: These big-headed know-it-alls have swollen brains (and egos) that afford them telekinetic power. Sadly, their sense of humour seems to be underdeveloped.
 * The Brain: This cunning ghost is the most evolved of all the Poltergeists. He awaits ghost hunters who are both brave and smart enough to match his powers.
