Piranhacus Giganticus

Piranhacus Giganticus are extra-large Piranha Plants 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. They also appear in larger Warp Pipes than other Piranha Plants.

Piranhacus Gigantici appear alongside Grand Goombas, Grand Paragoombas, and Gargantua Koopa Troopas in the Wii game, Super Mario Galaxy 2, where they appear in the Supermassive Galaxy. However, in contrast to their original appearance in Super Mario Bros. 3, they are invincible, thus serving more as an obstacle than an enemy. They can, however, be stunned with a Spin or a Star Bit, but that just hinders the player as it stops the plant from going back in the pipe.
