Mummy

"Those ghosts pretending to be mummies-what a hoot!"

- Professor E. Gadd

Mummies are ghosts disguised as such that appear in Luigi's Mansion: Dark Moon and Luigi's Mansion 3. They are usually found in desert-like locations.

Luigi's Mansion: Dark Moon
In Luigi's Mansion: Dark Moon, mummies first appear in the Old Clockworks during the mission, Underground Expedition. They slowly walk towards Luigi, and once they are close enough, they try to grab him, causing 20 damage if successful. Luigi must remove their mummy wrappings, as they cannot be sucked up into the Poltergust 5000; if a Strobulb charge is used on one, it will charge a small distance directly at Luigi, and if it hits a wall, it will collapse and one of its wrappings will come loose. Luigi must use the Poltergust 5000 to suck up the loose wrapping, use a Power Surge and the wrappings will fly off, revealing a Greenie utilizing fake arms and stilts. If Luigi is not fast enough, it will get back up. Alternatively, Luigi may also shine the Strobulb while he is behind a source of fire; if the mummy runs into the fire, its disguise will immediately be burned away, revealing the Greenie. After this, the Greenie will act normally.

In certain missions of the Treacherous Mansion, mummies make a reappearance, with Strong Greenies under the wrappings instead; otherwise, they act the same.

Luigi's Mansion 3
Mummies return in Luigi's Mansion 3, where they appear inside the pyramid in the Tomb Suites and rarely in the Master Suite. In this game, mummies can have either Goobs or Slinkers inside of them, or in one case, a Golden Goob. They have the same behavior as they do in the previous game and can be defeated the same way. There are additional ways to defeat them. Bursting once causes them to stumble and another Burst knocks them over. Slamming a ghost into a mummy also has the same effect. The Boo-faced boulder in the Tomb Suites pulls off their wrappings as well.
