Super Mario Sunshine is James The Bunny's favorite video game. The game was released for the Nintendo GameCube on July 19, 2002. It was the first Mario title on the GameCube (not counting Luigi's Mansion). This game got mixed reviews from critics, but James The Bunny doesn't care because it will probably always be his favorite video game of all time, no matter what. Also, not to generate confusion, Pokémon is James The Bunny's favorite video game franchise.
Mario, Princess Peach, and Toadsworth go on vacation to Isle Delfino, but discover that the island is polluted with graffiti from Shadow Mario, who is later revealed to be Bowser Jr. (spoilers!) It's up to Mario and F.L.U.D.D. (Flash Liquidizer Ultra Dousing Device) to clean up the graffiti and save Isle Delfino.
