Gooper Blooper Volley
Gooper Blooper Volley is a Special Game in Mario Power Tennis. It was set on the Gooper Blooper Court, situated in Ricco Harbor on the platform where Gooper Blooper is fought for the second time in Super Mario Sunshine. Gooper Blooper appears as the opponent, using all four of his tentacles to volley the tennis ball back to the player. The player must avoid hitting an area of the court marked with a cross - for that will give the player an instant game-over. When Gooper Blooper volleys a ball, he drops a racquet, and uses one of the different-coloured boxes by the side of him to fetch another one. The color of the square that the ball bounces in determines which racket Gooper Blooper hits the ball. A game similar to Gooper Blooper Volley is found in Mario Tennis Open called Ink Showdown.
In the Wii version, players get two extra chances before they fail.
