Gooper Blooper

Gooper Blooper is a giant Blooper that first appears as a boss in Super Mario Sunshine, where he appears in the levels Ricco Harbor and Noki Bay. He uses his tentacles to smack Mario, draining the plumber's health points. He also sprays goop for Mario to clean.

''Super Mario Sunshine
Gooper Blooper makes his debut in Super Mario Sunshine. The ill-fated Blooper is one of the monsters chosen by Bowser Jr. to help him frame Mario. Under Jr.'s command, Gooper Blooper takes over the market area of Ricco Harbor. Mario however comes to stop the monster. While hiding under a mountain of crates, Gooper Blooper leaves one of his tentacles sticking out, and not knowing what it is, Mario pulls on the tentacle and breaks it off of Gooper Blooper's body.

Enraged, Gooper Blooper attacks using his tentacles but despite his tries to defeat Mario, each one of his tentacles meets the same fate as the first. Before Mario pulls the cork out of Gooper Blooper's mouth he must first wash the black ink off. Mario also pulls the cork out of Gooper Blooper's mouth, causing ink to spray all over Gooper Blooper and the surrounding area. After the cork is gone, Mario can pull Gooper Blooper's mouth, before letting it go to snap back into his face like elastic, causing severe harm to the boss. After his mouth is pulled twice, Gooper Blooper is beaten and he blasts off into the sky, then lands in the part of the sea covered in goop.

However, Gooper Blooper survives and is fought the same way with re-grown tentacles in Ricco Harbor, this time on the helicopter pad. When not sprayed by water during this point, Gooper Blooper spins around hitting the player with his tentacles. Once the same tactic is used again, Gooper Blooper is blasted off into the sky and crashes into the sea.

Gooper Blooper resurfaces in Noki Bay on the peak of the mountain. This time upon defeat, he crashes into the mountain side.

''Mario Power Tennis
Gooper Blooper reappears in Mario Power Tennis where he is the opponent in the mini-game Gooper Blooper Volley. All four of his tentacles wield a tennis racket. Here, the player attempts to hit a tennis ball between them and Gooper Blooper while avoiding the crossed-out panels. Gooper Blooper is shown to be quite skilled at the sport, though this may be because of his 4 tentacles. Also, at the beginning of the mini-game, the tennis ball comes out of Gooper Blooper's mouth.

''Super Princess Peach
Gooper Blooper appears again in Super Princess Peach as the fifth Boss in the game and is damaged by whacking his tentacles and mouth with Perry. After he loses three health points, he uses the Calm vibe to fall asleep and regain health. Peach wakes him up with the Rage vibe and takes out his remaining two health points. He is larger in this game, compared to others.

''Mario Hoops 3-on-3
In Mario Hoops 3-on-3, Gooper Blooper appears in the court called Pirate Ship. His task is similar to the mythical monster, the Kraken, by surrounding the ship in a menacing way and attacking all passengers of the boat. Gooper Blooper smacks the player with his tentacles if the player gets too close to the edge. Due to the fact that the sky is dark and stormy and that he isn't right at the side of the boat, Gooper Blooper may be hard to notice.

''Mario Super Sluggers
Gooper Blooper appears again in Mario Super Sluggers as a hazard in the mini-game Blooper Baserun where players must dodge his tentacles and collect coins. He also appears around the Daisy Cruiser stadium at night, and grabs the ship and tilts it to its side. He seems to be bigger in this game than in the previous ones. This game is also the first game to depict Gooper Blooper swimming in water, as in his first appearance in Super Mario Sunshine, he disappeared when he touched it, though it might have to do with the fact that the Ricco Harbor's water was polluted at the time.

''Mario & Sonic at the London 2012 Olympic Games
Gooper Blooper returns once again in Mario & Sonic at the London 2012 Olympic Games, where he is the final obstacle in the Dream Rafting competition. When faced, Gooper Blooper traps the competitors' raft in a whirlpool and will try to slam down on them with his tentacles. If the player dodges it successfully they can use this chance to jump attack his tentacles. Once all four tentacles are jumped on, Gooper Blooper will begin to quiver in pain and leap into the air, landing back down in the water defeated and dazed. A remixed version of his original boss music from Super Mario Sunshine is used during the battle.

Abilities
Gooper Blooper can use all his tentacles to his advantage, whether it be slamming them all down on Mario at once or just slamming one down. Gooper Blooper will also twirl around swinging his tentacles hurting anyone who gets in their path. Gooper Blooper is also very strong as he can tilt the entire Daisy Cruiser to one side. Like all Bloopers, Gooper Blooper can spit out ink to cause a slippery mess, and he can swim in unpolluted water as well. He can also jump very high which is shown in "Gooper Blooper Breaks Out". However, Gooper Blooper has never shown the ability to speak or walk on land. He has also been shown to be very adept at playing tennis, as in Mario Power Tennis, the player can continue volleying a tennis ball between themselves and Gooper Blooper for virtually ever.

Trivia

 * In the beta version of Super Mario Sunshine, Gooper Blooper was dark blue. Its appearance was later changed to its current coloration for unknown reasons, possibly to make him look more like a regular Blooper. His strange blue color could also have been generated by technical difficulties.
 * It is possible to beat Gooper Blooper without pulling off any tentacles. The player must spray Gooper Blooper so all the goop is off his mouth and pull it while his tentacles are on the ground.
 * The only game in which Gooper Blooper has a cork in his mouth is Super Mario Sunshine.
 * Another "Giant Blooper" boss appears in the Paper Mario series. In Paper Mario: The Thousand-Year Door and Super Paper Mario, this "Giant Blooper" takes on Gooper Blooper's French name.
 * Mario & Sonic at the London 2012 Olympic Games is the only game that Gooper Blooper appears in that Petey Piranha does not.
