Lava Piranha
An enormous overgrown Piranha Plant who lives within the confines of Mount Lavalava in Paper Mario and guards Misstar, the fifth Star Spirit.
Lava Piranha speaks in hacks and shouts, and always seems to be smiling, even when defeated.
Interestingly, according to Goombario, the Lava Piranha isn't a unique being, but a variety of Piranha Plant found in the Mushroom World. This means there may be more than one Lava Piranha! Goombario's refers to Lava Piranha in the plural from, meaning there are multiple Lava Piranhas.
Additionally, the Lava Piranha bears a strong resemblance to the Naval Piranha from Super Mario World 2: Yoshi's Island, causing many to mistake the character. They are probably very closely related to them.
