Bone Piranha Plant

The Undead Piranha Plant is an enemy appearing in New Super Mario Bros. 2. Appearing in Towers, it seems to be a palette swap of the standard Piranha Plant, able to be defeated with fireballs and immune to jumps, and having the same behavior, planted in the ground and biting in random directions. It appears similar to a Dry Bones, being skeletal. This is unusual, as plants do not have skeletons in the Real World.
