Froggy

Prince Froggy is the ruler of a a large swampy area on the Yoshi's Island. He's the midpoint boss of World 3 in Super Mario World 2: Yoshi's Island, and offers a truly unique challenge. When you engage him in combat Kamek Koopa swoops in and shrinks you, then Prince Froggy swallows you down. The actual battle is between Yoshi and Froggy's uvula, and a whole lot of dripping stomach acid. In defeat Froggy poops you out back to normal size then lies down with some major intestinal pain. He reappears in Tetris Attack.

Prince Froggy is the king of Frog Pirates
