Bogmire is the ghost of the graveyard, who can be accessed by Spooky being sucked up into the Poltergust 3000 in the Boneyard. Luigi must then tap the largest grave after he deals with the two Skeleton Ghosts. After being unleashed, Bogmire jumps out of his gravestone and Luigi finds himself transported by him to a circular arena. Bogmire makes shadow versions of himself to attack. If these duplicates are curled into a ball and thrown at him, Bogmire becomes injured and becomes vulnerable to the Poltergust 3000. Luigi has to watch his movement when capturing Bogmire, as the boss can drag him into another enemy.
According to his picture description, Bogmire does not know what to fear or have despair about.
