Piranhacus Giganticus

A Piranhacus Giganticus is an extra-large Piranha Plant in the game Super Mario Bros. 3. They only appear in Big Island. Although they are huge, a single fireball will destroy them. Despite their size, they are essentially exactly the same as any other typical Piranha Flower, other than they present a larger target and obstacle.

Piranhacus Gigantici appear alongside Grand Goombas and Grand Paragoombas in the Wii game, Super Mario Galaxy 2, where they appear in the Supermassive Galaxy. They however in complete contrast to its Super Mario Bros. 3 orgins, are completly invincible being unkillable at all, thus serving more as an obstacle than an enemy. They can be stunned however with a Spin or a Star Bit, but that just hinders the player as it stops the plant from going back in the pipe.
