Petey Piranha first appeared as the primary boss of Bianco Hills in Super Mario Sunshine.
Petey Piranha is known as Boss Packun in Japan.
Normal Piranha Plants usually grow from pipes but Petey’s leaves and roots have grown into foot-like and arm-like appendages.
Petey is a larger and much more powerful version of a Piranha Plant which is the result of mutation.
Petey can use his leaves to fly around in the air.
He has also appeared as a boss in games such as Super Princess Peach, Mario & Luigi: Partners in Time, New Super Mario Bros and Super Smash Bros Brawl.
Petey Piranha also acts as a playable character in spin-off Mario games like Mario sports games and in Mario Kart Double Dash.
A dinosaur-like version of him called Dino Pirahna also appears as the first episode boss in Super Mario Galaxy.
