Bone Piranha Plant

The Bone Piranha Plant is a subspecies of Piranha Plant debuting in New Super Mario Bros. 2. It is a bony version of their relatives, with some changes:


 * A grayish cranium;
 * Holes rather than spots;
 * Greeny gray lips;
 * Vertebrae instead of a stalk;
 * Dark gray leaves.

Even with these graphic changes, its attack patterns are the same as those of a regular Piranha Plant, however, unlike normal Piranha Plants, they are immune to fireballs. They are only found in Fortresses and Castles.
