In this mission, Mario must defeat Petey Piranha within 300 seconds. Every time Petey Piranha rallies the ball, he loses a bit of health. Whenever Petey Piranha loses a full meter, he will fall over and his bellybutton will be exposed, which Mario needs to attack with a Zone Shot. Failing to hit the bellybutton will cause Petey Piranha to recover a bit of health and stand back up. Petey Piranha has three meters of health, indicated by hearts, and whenever he loses one, he will send out groups of tornadoes Mario has to avoid or jump over. Failing to rally a ball will subtract five seconds from the timer, and getting hit by a tornado subtracts ten seconds from the timer.
Afterwards, Mario will obtain the first Power Stone.
