Mr. Bones

thumb|Mr. Bones ghosts in the Graveyard. Mr. Bones are skeletal ghosts appearing only in the game, Luigi's Mansion. A skeleton ghost named Mr. Bones is first encountered in the Boneyard where it was disturbed by Spooky's barking. They attack by throwing bones at Luigi. Skeleton ghosts were found in the Graveyard and had to be defeated to lure out Bogmire. More skeleton ghosts were later encountered again in the Telephone Room. Mr. Bones has thirty HP. To defeat them, Luigi would have to catch him off guard, rebuilding himself and try and suck him up. Mr. Bones could also be defeated by one of the three Elements.

Trivia

 * Mr. Bones is similar to another skeleton enemy, Dry Bones, as they are both undead and attack by throwing bones. However, Skeleton Ghosts resemble a small human skeleton, rather than a Koopas.
 * The Mr. Bones in the Boneyard is the only known Mr. Bones who could talk. He is also the only non-portrait ghost to speak.
