Bony Beetles are bony Koopa shells with spikes on their shells. Like Buzzy Beetles, Bony Beetles are impervious to fire and have very high defense. Whenever attack, their spikes will pop in or out their shells and their power will increase or decrease. They can also be flipped over like regular Koopas and Buzzy Beetles, causing their defense to drop to 0. They appear in Bowser's Castle in the original Paper Mario, and occasionally are found in several locations in World 5 of Paper Mario: Sticker Star.
