When he falls, his belly button will be sticking out and Mario must ground pound it three times. In the other mission, Mario must squirt water in his mouth, waking him up. He will then fly around, and Mario must squirt water in his mouth so he falls and Mario must then ground pound him.

Mario & Luigi
Mario & Luigi: Partners in Time
In the Mushroom Kingdom's past, Princess Peach is sentenced to be fed to Petey Piranha in the Koopaseum by Princess Shroob's orders. Shortly before the execution, Mario, Luigi, Baby Mario, and Baby Luigi enter the Gritzy Caves beneath the Koopaseum to find Petey and save Peach, while also encountering Kylie Koopa, who two Shroobs have suspended by a rope. Petey then emerges from the ground and the Shroobs cut Kylie's rope, feeding her to Petey as well as the princess. But before the Mario Bros. can do anything, he burrows away. They later encounter him in the Gritzy Desert as the game's third major boss. Once defeated, Petey Piranha explodes and both Kylie and a Cobalt Star Shard fly out of him, but Peach does not. Kylie explains that when she was eaten, she saw the princess, but Petey spat her out right after swallowing Kylie.
Mario & Luigi: Paper Jam
Petey Piranha and his Paper counterpart appear in the game as the first and fourth boss respectively. In the first fight against regular Petey Piranha, he will try to grab and eat Mario, Luigi, or Paper Mario, but by jumping at the right moment, he will spin around and fall over, with his unprotected belly being his weak spot. When Petey's health reaches halfway, he will try to spit goop at the Mario brothers, but he can be outran using Paper Mario's airplane mode. Paper Petey Piranha fights similarly, except he steals Paper Mario's Copy ability to make clones of himself. When enough damage is dealt, the copies drop on the floor. Only the true Paper Petey Piranha will take damage, which can be identified when he lifts his head.
