Big Bone Piranha Plants are the giant versions of Bone Piranha Plants. Like all the other undead enemies from New Super Mario Bros. 2, they are similar to their non-undead species, with the same strengths and weaknesses. Like many of the other enemies in this game, Mario and Luigi can defeat this enemy with a single gold fireball and receive Coins. Like normal Bone Piranha Plants, it cannot be harmed by fire, but can be destroyed with either a Super Leaf, Gold Flower, Mega Mushroom, or a Star. They appear in World Mushroom-Castle, World 4-Fortress and World 5-Castle.
