Lava Piranha

Lava Piranha appeared in 2000 video game called Paper Mario. Lava Piranha is an enormous Piranha Plant boss in Paper Mario who, as its name suggests, dwells in a pool of lava. Lava Piranha bears some resemblance to the boss Naval Piranha from Super Mario World 2: Yoshi's Island, except smaller and with fewer buds and tendrils. Lava Piranha has a large tongue and white ring markings instead of filled white spots on its head, like typical Piranha Plants.

Goombario and Koopa Koot refer to Lava Piranha in plural terms, suggesting there is more than one Lava Piranha in existence. Given its Japanese name, this is likely referring to Fire Piranhas.
