Polterpups are medium-sized, ghost dogs that appear in Luigi's Mansion: Dark Moon. They are one of the many ghosts living in Evershade Valley, and are normally friendly, but when the Dark Moon shattered, they started causing mischief. There is one main Polterpup character named Polterpup that appears throughout story mode, but other Polterpups only appear in some locations of Haunted Towers.
