Lava Piranha

"WE MAKE THINGS HOT FOR YOU! WE BEAT YOU, MARIO!"

- Lava Piranha

Lava Piranha is an enormous Piranha Plant boss in Paper Mario who, as its name suggests, dwells in a pool of lava.

Paper Mario
The Lava Piranha featured in Paper Mario is the ruler of Mt. Lavalava on Lavalava Island. It is found in a small lava pool where the other Piranha Plants report to him.

Lava Piranha speaks in shouts and shrieks, blathering out insults at Mario when it confronts him for the fifth Star Spirit, Misstar, whom Bowser ordered the fiery Piranha Plant to guard. Its attacks are rather simple. Most of its attacking is done via Lava Buds. When it attacks, it spits out an orb of fire at Mario that does five attack damage to Mario.

After Mario initially defeats Lava Piranha, it suddenly emerges from the lava and gets forty more HP. This time, Lava Piranha's head is on fire and its tongue is sticking out. If Sushie is Ultra-rank, her Tidal Wave ability makes this second phase easy, and possible to beat without taking any damage, as water and ice attacks stun it for two full turns. After the second round, it slowly falls to the ground and then sinks back into the lava, relinquishing the Star Spirit.

It has a cameo appearance in the credits of Paper Mario, poking its head out from behind Lavalava Island, alternating with Raphael Raven.

In Super Mario-Kun, the Lava Piranha is encountered after Sushie destroys a Spiny Tromp. Mario and his partners attempt to attack it by using a Snowman Doll, but it results in Kooper getting crushed. The Lava Piranha then spews Lava Buds that attack Mario and his partners. Sushie then encases Mario in Water Block and squirts Lava Piranha. Mario walks out of the water block and shouts, distracting Sushie. Lava Piranha then burns and injures Sushie. Despite this, Sushie inflates Mario with water and pushes him to Lava Piranha. Mario bursts, spraying the water over Lava Piranha and thus defeating it.

Appearance
Lava Piranha bears some resemblance to the boss Naval Piranha from Super Mario World 2: Yoshi's Island, except smaller and with fewer Piranha Buds and tentacles. Lava Piranha has a large tongue and white ring markings instead of filled white spots on its head, like typical Piranha Plants.

Trivia

 * 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. So far, standard Fire Piranhas have yet to be shown within lava in the Mario series.
 * Lava Piranha being the boss of the fifth chapter in Paper Mario:, encountered in the volcanic Mt. Lavalava of the tropical Lavalava Island, mirrors how Petey Piranha is the boss of the fifth world in Paper Mario: Sticker Star, and is encountered in a volcano in a tropical jungle. As well, both characters are Piranha Plants.
