Petit Piranha

Petit Piranhas are enemies featured in Paper Mario.

These small little baby Piranha Plants are only fought once in the entire game, during the boss battle with Lava Piranha. These little guys are budding off of him. Once Lava Piranha is defeated the first time, these two will also catch on fire, making them more of a threat as well. However, this makes them vulnerable to water and ice attacks like Lava Piranha, himself.

These guys aren't the type to battle as they only have 1 Hit point. Simply attacking them and lowering that number to zero prevents them from attacking for a couple of turns.
