Mummies are ghosts wrapped in mummy tape that appear in Luigi's Mansion: Dark Moon and Luigi's Mansion 3. They are introduced mid-game and compared to their original counterpart are the most varying type of ghost.
Luigi's Mansion: Dark Moon[]
Mummies first appear in the Old Clockworks, in the Tomb, during the second mission.
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. If Luigi is not fast enough, it will get back up.
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 (or Strong Greenie in later parts of the game), which is holding fake arms and legs.
Alternatively, if the mummy runs into a source of fire, its wrappings will automatically burn off, revealing the Greenie.
Luigi's Mansion 3[]

Mummies return in Luigi's Mansion 3, where they appear inside the pyramid in the Tomb Suites. They have the same behavior as they do in the previous game. Here, mummies can have either Goobs or Slinkers inside of them, or in one case, a Golden Goob. They also appear in the Master Suite. There are more ways to defeat them here. Bursting once causes them to stumble and another Burst knocks them over. Slamming a ghost into a mummy also has the same effect. The large Boo Ball in the Tomb Suites pulls off their wrappings as well.
Mummies have a second layer of behaviour in which that they follow to the last place Luigi makes a sound. Running or the use of the poltergust classifies as a sound. If Luigi does not make a sound, he will effectively be invisible.
