Peewee Piranha

Peewee Piranha is a boss appearing in the game Super Mario Galaxy 2. It appears in the Sky Station Galaxy. Mario first encounters the creature enclosed in an egg, much like the Dino Piranha in the first game. The boss looks like the Dino Piranha except it has a pink head, green petals, two appendages, and its backside is protected by the eggshell. Peewee Piranha attacks mainly by charging at Mario. Mario will need to hit the shell to expose its bulbous and throbbing rear. After Mario hits the Peewee Piranha from behind once, it will reform its shell for protection and begin to charge at Mario again. Its attacks are now much faster and it can also lunge at the plumber. Mario will need to hit the eggshell three more times to let exposed its throbbing rear to be hit again, and be defeated, granting Mario the Power Star. So far this boss is confirmed for the mission "Peewee Piranha's Temper Tantrum".
