Petey Piranha

Petey Piranha ("Boss Pakkun" in Japan) is a giant Piranha Plant that first appearing as the boss of Bianco Hills in Super Mario Sunshine that Mario had to defeat two times.

The First Fight
In Mario & Luigi: Partners in Time in the past of Koopaseum, Petey ate Princess Peach and Kylie Koopa. Mario, Luigi, Baby Mario and Baby Luigi went into the caves and fought him to save Peach and Kylie.

While Luigi and the babies were meeting him and fighting him for the first time, Mario had already fought him before, however since this was the past, Petey did not know Mario.

Petey Piranha was defeated and he disappeared. While many fans wonder what he was doing in a desert and what he was doing in the past, fans say that this might be his father, or Petey Piranha was created by the Shroobs.

In Isle Delfino
In Super Mario Sunshine, Mario fought inside the Windmill and when everyone thought he was gone for good, Petey Piranha came back later, where Mario again had to defeat him, but this time in Bianco Hills, not in the Windmill!

Petey attacks by shooting goop that makes other enemies and making tornadoes. Later in the second battle he can fly around, and Mario has to get him down from the air to fight him.

Fans back then thought that Petey was made by Bowser or Bowser Jr.'s magic, however later in Partners in Time since he appeared in the past, it remained a question.

Petey in the Ice World
In New Super Mario Bros., Petey Piranha is the boss of World 5, the ice world. Petey attacks by flying up high, then dropping from the sky, crushing any opponents beneath him with a move similar to the ground pound. Since the floor is made of slippery ice, after attacking he will slip and fall. It is then that he can be attacked. If Mario or Luigi can defeat him using a Mini Mushroom, they will travel to World 7 instead of World 6.

Petey Piranha Returns
Even if he was said to be defeated, Petey appeared as a boss in Mario Pinball Land and Super Princess Peach. Peach had to cry so the water would inflate him and make him fall down and reveal his weak spot: his belly button.

Later, Petey started playing sports with Mario and his friends. He first showed up as an unlockable character in Mario Golf: Toadstool Tour, in which his large size made him the most powerful golfer in the game. In Mario Power Tennis, Petey's bulk served him well again, as he was one of the more powerful competitors. His special attack involved swallowing his racket, puking it up, and spitting it at the ball at a high speed.

Finally, Petey had the ability to body check other players in Mario Superstar Baseball, making him an effective character in close plays.

Petey also appeared in Mario Kart: Double Dash with King Boo as his partner. They both had the ability to use any character's special item. Because of this advantage, some players refuse to play in his presence. Petey's personal kart is the "Piranha Pipes", a vehicle assembled out of the Piranha Plant's trademark green tubing.

Strangely two Petey Piranha-like characters appear in the Daisy Garden court as the basket in Mario Hoops 3-on-3 and try to keep anyone from making a slam dunk. It is possible that these are Piranha plants of the same species as Petey, and that Petey is a species and maybe the Peteys Mario has fought before are not always the same, explaining why he always died and came back.

Physical Description
Petey could be recognized as a Piranha Plant, but looks a little different from a normal one. According to Mario Superstar Baseball, Petey Piranha got his looks from a mutation of an unknown source, possibly the Shroobs. He has leaflike arms and stubby legs unlike normal Piranha Plants. He also has a ring of flowers around his head and is bigger than most Pirahna Plants.

Abilities
Petey Piranha got his abilities from a mutation of an unknown source, possibly the Shroobs. It is possible he used to be a Piranha Bean that became a mutant by the Shroobs. His leaves double as wings, something normal Piranha Plants cannot do. In Super Mario Sunshine he could spit out goop from his mouth. The goop was slippery and enemies spawned from it. In Mario and Luigi: Partners in Time he could dig though sand and spit out a Piranha Plant seed which would sprout and attack the players.

Sports Info
When Petey hits the ball with his club in Mario Golf: Toadstool Tour it goes blasting off the course in a golden streak. When he's playing baseball, he catches and throws the ball with his mouth, but when he's batting he hits the ball with his leaf-like arm. His sweet spot is the vein of his arm.

Super Smash Bros. Brawl
Some people believe that because Petey Piranha appears in so many games in the Mario series, he could appear in Super Smash Bros. Brawl as a playable or non-playable character.

Trivia

 * It is unknown, but Petey Piranha may be native to the Beanbean Kingdom. In Mario and Luigi: Superstar Saga, a Beanbean Piranha Plant known as a Piranha Bean appeared, which appears to be the same species as Petey. There is no solid evidence for this theory.
 * Petey also resembles the giant piranha plant like monsters from Super Mario Land 2: 6 Golden Coins. The Golden Coin Piranha is tall, spotted and shots giant fireballs.
