Polterpup (species)

Polterpups are ghost dogs in Luigi's Mansion Dark Moon. These dogs take various objects of importance that Luigi needs. These range from Keys to Gold Dog Bones. A Polterpup may also revive Luigi, who has lost all of his HP, if Luigi happens to have a Gold Dog Bone with him. When a Polterpup has taken something, the player must track it down using the Dark Light function. When the Polterpup is found, they must suck it up. Upon being sucked up, their color changes to gold.

Polterpups also appear in a specific multiplayer mode called Polterpup Mode. In this mode, the group must find the kennels or locations where the Polterpups are hiding and acquire them all. Each Polterpup has 50 HP, except for the blue collared one that is twice the size of a normal Polterpup, which has 100 HP.

In the game's ending, it is shown that Luigi keeps a Polterpup for his own at his house.

Trivia

 * A Swapnote message regarding Luigi's Mansion: Dark Moon was sent by Shigeru Miyamoto prior to the game's release. According to the note, the Polterpup is Miyamoto's favorite ghost in the game.
