Petey Piranha

Petey Piranha is a large Phirana Plant, and one of the first bosses in Super Mario Sunshine. Since then he has become a regular boss character in many other Mario titles, such as Mario Pinball Land, Mario & Luigi: Partners in Time, Super Princess Peach, New Super Mario Bros., and Super Smash Bros. Brawl. He has also played a role in the games Mario Kart: Double Dash!!, Mario Strikers Charged, Mario Golf: Toadstool Tour, Mario Superstar Baseball, and Mario Power Tennis. He has multiple special powers that set him apart from normal Piranha Plants, including spitting Goop and flying.

Super Mario Sunshine
Atop the windmill of Bianco Hills is Petey, who is responsible for the huge mess plaguing Bianco Village. When the player reaches the top, Petey will collapse the roof of the windmill, plunging Mario and Petey in, initiating the Boss battle. To defeat him, Mario must fill his mouth with water (using FLUDD) until he falls over then Ground Pounds his belly. He also appears later in the game as another boss, but this time he can fly. Mario must, again, fill Petey's mouth with water when it's open until he falls down and Ground Pound his belly again.

Super Smash Bros. Brawl
Petey Piranha makes an appearance as the first boss of the Subspace Emissary. In the game, he'll trap both Princess Peach and Zelda into cages, then will attempt to take on Kirby or Mario. Depending on which character you choose to play as, Kirby or Mario will then be required to save one of the princesses, with the other one ultimately being turned into a trophy afterwards by Wario.

Petey Piranha's Trophy is obtainable by throwing a Trophy Stand at him during battle.
