Strong Poltergeist

The Strong Poltergeist (Strong Boffin in the British English version) is a sub-boss fought in the Treacherous Mansion in Luigi's Mansion: Dark Moon.

Appearance
The Strong Poltergeist resembles a normal Poltergeist, but has the stony texture on them, like all other strong ghosts have.

Battle
For Luigi to gain access to the Strong Poltergeist, the player must head to the Space Exhibit, and look into the moving telescope. After looking out of it, Luigi will be teleported into space. During battle, the Strong Poltergeist attacks by throwing stars at Luigi. The player can tell where the Poltergeist is by the stars lighting up. When it is not holding a star, the player can stun it using the Strobulb and capture it. The Strong Poltergeist has 200 HP. While capturing it, the rocks start spinning, causing Luigi to lose his suction and freeing the Poltergeist. The Poltergeist will enter the aestroid and spinning it, throwing bombs out of it, and also Beetles as well. Once the Poltergeist is defeated, Luigi is teleported back into the Space Exhibit and the yellow book is obtained.
