Poltergeist

Poltergeist (called Boffin in, certain countrys, PAL versions) is a mini-boss in Luigi's Mansion: Dark Moon. 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. The Poltergeist can also be encountered as a boss on the ScareScraper under the name of The Brain. The Brain is the same as the regular Poltergeist except it has 300 HP and is much larger than normal.

Ghost Container Description
''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.''

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