Polterpup (known as ??? in E. Gadd's Vault) is a ghostly dog who appears throughout Luigi's Mansion: Dark Moon and Luigi's Mansion 3. His name is a portmanteau of "poltergeist" and "pup." Polterpup is notably the only ghost that Luigi does not show any fear of in Luigi's Mansion: Dark Moon. Instead, Luigi either is friendly toward him or views him as a mere nuisance, the latter of which is evident when he says, "Bad doggie!" whenever Polterpup ends up stealing important keys.

Multiple Polterpups have been shown in the multiplayer ScareScraper mode in Luigi's Mansion: Dark Moon. These Polterpups wear blue collars instead of red collars. Big Polterpups additionally appear in the mode.


Luigi's Mansion series[edit]

Luigi's Mansion: Dark Moon[edit]

The rehabilitated Polterpup with Luigi at the end of Luigi's Mansion: Dark Moon

Polterpup first appears in the Gloomy Manor, where he is playing in the Mudroom Exterior and discovers an amethyst after digging around the ground. While briefly playing with it, Polterpup winds up getting the amethyst stuck in a tree, after which he leaves the Gloomy Manor.

Later, Polterpup appears in the Haunted Towers during the mission Pool Party. After Luigi finds the special key in the pool, Polterpup runs up and playfully takes away the key. However, unlike with his fellow ghosts, the absence of the Dark Moon's pacifying effects renders Polterpup nonviolent and mischievous, rather than hostile and aggressive. This is evident when Luigi briefly plays with him, and in the event Luigi loses all of his Heart Points, Polterpup even licks him back to health as long as Luigi has a Gold Bone.

After Polterpup steals the special key, Luigi has no choice but to chase after him in the mission Doggone Key to retrieve the key. Luigi finally catches him, but before he can store him in the Ghost Container, Polterpup manages to escape from the Poltergust 5000 and flees yet again. It is at this point that Professor E. Gadd surmises that Polterpup is lonely and is looking for someone to play with, even if his attempts to do so unintentionally cause trouble for Luigi.

Polterpup returns in the Old Clockworks during the mission Play Catch, where he steals the second clock hand from a group of Greenies and swallows it whole. Luigi has to chase after him yet again before finally catching him in the Poltergust 5000. Despite this, Polterpup manages to escape yet again before he can be stored away. Polterpup returns yet again in the Treacherous Mansion during the mission Front-Door Key. Just before Luigi can go through the front door, Polterpup jumps out of the keyhole and knocks the key out of Luigi's hand. He flees to the mansion's basement, forcing Luigi to track him down again. This time, Polterpup is able to be properly kept within the Ghost Container thanks to E. Gadd's repairs.

Following King Boo's recapture and the Dark Moon's restoration, Polterpup and his fellow ghosts are finally released from the Ghost Container. Upon being released, he unhappily approaches Luigi in acknowledgement of having caused his fair share of trouble during the absence of the Dark Moon. However, Luigi nevertheless cheers Polterpup up, much to his delight. After Polterpup takes a celebratory photograph alongside Luigi, Mario, E. Gadd, the Toad assistants, and a few of his fellow ghosts, he is adopted by Luigi and accompanies him back to his home as his new pet.

Blue collar version as seen in the ScareScraper mode

Polterpups as a species appear only in the ScareScraper in their own mode: Polterpup Mode. In Polterpup Mode, the Luigis must cooperate and capture all Polterpups on the floor by using their Dark-Light Devices to see the footprints. Once a Polterpup has been located, it 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. Regular and Big Polterpups in the ScareScraper mode always drop a Gold Bar when captured, even if the Poltergust 5000 is at minimal power. This means that they 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.

Luigi's Mansion (Nintendo 3DS)[edit]

Despite not appearing in the original Luigi's Mansion, Polterpup appears in the Nintendo 3DS remake. When Luigi's amiibo is scanned, Polterpup appears when Luigi has lost all of his health and eats a Gold Bone to recover Luigi.

Luigi's Mansion 3[edit]

Polterpup returns in Luigi's Mansion 3, this time as a tutorial guide. He remains as Luigi's pet and accompanies him and the others to The Last Resort. After Luigi narrowly escapes to the hotel's basement from King Boo, Polterpup wakes Luigi up by licking his face. He then shows Luigi where the new Poltergust G-00 is and teaches him how to use it. Later, when the ghost Clem floods the Reservoir and Luigi can hardly swim with the Poltergust weighing him down, Polterpup pulls him out of the water. Later, Polterpup searches together with Luigi for Polterkitty after she swallows an elevator button for the second time, and assists him in reaching two of the captured Toads after the respective boss fights. At the end, Polterpup unintentionally saves Luigi from King Boo by pushing him aside before he is caught in a painting with Mario and Princess Peach (he was chasing a bat when he jumped onto Luigi). When the hotel collapses, Polterpup saves Luigi for the second time by catching him before he falls to the ground. In the end, he goes back with Luigi to the Mushroom Kingdom.

At the end of Luigi's Mansion: Dark Moon, Polterpup gains pupils like the other rehabilitated ghosts and retains them when he goes to live with Luigi. However, in Luigi's Mansion 3, despite his rehabilitation, Polterpup no longer has pupils. In the FAQ section of the guide in Luigi's Mansion 3, Professor E. Gadd states that he is researching what breed of dog Polterpup is and guesses that he is "...something like a silver retriever!"

Super Smash Bros. series[edit]

Polterpup appears as a trophy in Super Smash Bros. for Nintendo 3DS and as an Advanced-level, support spirit in Super Smash Bros. Ultimate.


Polterpup typically acts like a normal dog and is playful, loyal, and energetic. Unlike the other ghosts in Luigi's Mansion: Dark Moon, Polterpup is friendly and harmless and acts more like a nuisance than a threat to Luigi during his quest to retrieve the pieces of the Dark Moon. By the end of the game, Polterpup is remorseful of his actions and is quick to recover from his sadness, especially after befriending Luigi. E. Gadd speculates Polterpup is lonely, and his interactions with Luigi could have been a desire to gain the attention he craves. After Luigi adopts him, he develops a strong sense of loyalty towards Luigi.

This loyalty is expanded upon in Luigi's Mansion 3, where Polterpup acts like a guide to Luigi in the beginning of the game and occasionally comes to Luigi's rescue when he is in true danger, including saving him from drowning and falling. Polterpup's mischievous and hyperactive behavior still is intact as shown when he eats Mario's cake and appears randomly, unintentionally, spooking his owner. Other than his master, Polterpup is extremely friendly and loving towards those around Luigi, perking up and smiling around them, and is willing to befriend Polterkitty, only to be rejected by her, which saddens him.

If you combine a puppy and a ghost, you'll get a cute little Polterpup. They seem to enjoy causing no end of trouble, but I couldn't tell you if they're enemies or just really mischievous. This big guy's a lot bigger than normal—hopefully he just wants to be friends? (American English)
This little guy...or girl – who can tell? – is always finding ways to cause mischief, but it's not clear whether he's your friend, your foe, or just a crazy critter who can't decide one way or the other. Still, as much of a handful as this pup can be, he's nothing compared to Big Polterpups! (British English)
