Polterpups are small, ghostly dogs that appear in Luigi's Mansion: Dark Moon. They are one of the many ghosts living in Evershade Valley, and are typically friendly, but when the Dark Moon shattered they became very mischievous. There is one main Polterpup that appears throughout story mode, but other Polterpups only appear in the ScareScraper.
In the ScareScraper mode, they are featured in their own mode: Polterpup Mode. In Polterpup Mode, the Luigis must hunt down as many Polterpups as possible by using their Dark-Light Devices to see the footprints. Once a Polterpup has been located, he must be flashed with the Strobulb and vacuumed up. Each Polterpup has 50 HP, but Luigi can find a Big Polterpup, which has 100 HP.
Unlike the Polterpup in Dark Moon Quest, or any other ghost in the game, regular and Big Polterpups in ScareScraper always drop a Gold Bar when captured, even if the Poltergust 5000 is at minimal power. This means that they will drop an additional Gold Bar on top of whatever Power Surge a Luigi uses to drain its health, from two Gold Bars from a Blue Surge up to four from a Red Surge. A Polterpup drops five Gold Bars if it is captured with another ghost from a Red Surge.
Polterpups are white, canine-like ghosts that wear either red or blue collars. Like most other ghosts, they are slightly transparent. Polterpups' eyes are white and opaque, which makes them stand out more against their transparent bodies. Unlike real dogs, Polterpups lack ears, thus their head is completely round.
 Ghost Container Description
Polterpup: Normally very playful and kind, the Polterpups started misbehaving after the Dark Moon shattered.
Big Polterpup: This pooch is big, so it might take more than one ghost hunter to keep him under control!
