Super Mario Sunshine is a 3D action-adventure platformer game released in 2002 for the Nintendo Gamecube. It is the second 3D Mario platformer after Super Mario 64. Mario, Princess Peach, Toadsworth, and some Toads go to Isle Delfino for a vacation. After arriving, they learn that graffiti is polluting the island, which drives away the Shine Sprites, thanks to a Mario impostor. The real Mario is accused and sentenced to clean up the mess. With help from a device named F.L.U.D.D., Mario cleans the goop, gathers the Shine Sprites, and seeks to clear his name.
The boss of Bianco Hills (Episode 2) is Petey Piranha. When fighting Petey Piranha, Mario has to shoot water into his open mouth. Petey becomes bloated and falls over, giving Mario a chance to ground pound his exposed navel. If the player does not ground pound the belly quick enough, Petey will expel the water, forcing the player to repeat the process. Humorously, the player can inflate Petey without making him fall over, by stopping before he gets too full, letting the battle continue. This does not affect the battle in any way.
Petey Piranha returns as the boss of Episode 5 ("Petey Piranha Strikes Back").
Poinks are pig-like creatures that only appear in Episode 5 of Bianco Hills, and during the boss battle with King Boo, during Episode 5 of Sirena Hotel. If Mario gets near some Poinks, one will attach itself to F.L.U.D.D.'s nozzle. Squirting water causes the Poink to expand and stay attached. At its fullest the Poink will not explode, nor will it inflate any further. Releasing the "R"-trigger makes the Poink shoot off in Mario's direction, bursting when it comes into contact with another creature or surface.
One of the enemies, a Piranha Plant can be inflated using F.L.U.D.D.
- Even though Petey Piranha is the boss of Episode 2, the player can fight him in Episode 1 by climbing up the windmill like normal.
