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, 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.
Piranhacus Giganti also appeared in New Super Mario Bros. Wii, but unlike the ones in Super Mario Bros. 3, in order to kill them, they have to be fired with multiple fireballs using the Fire Flower
