Choropū Men'iwa

Monty Mole stone spirits are undead variants of Monty Moles that appear in volume 5 of Super Mario-kun. They resemble stones with Monty Mole faces.

When Mario is in the graveyard, he meets the Monty Mole stone spirits alongside other stone spirit enemies. They fly towards Mario before attacking him. Mario opens Yoshi's mouth to make him eat the stone spirits, then punches Yoshi's mouth to break them. The spirits of the enemies including the Monty Moles fly out, now resembling ghosts.
