Jean de Fillets appear in two levels of Super Mario World 2: Yoshi's Island and the exclusive Endless World of Yoshis stage in Yoshi's Island: Super Mario Advance 3. Despite being a Flopsy Fish's skeleton, a Jean de Fillet is larger than it. Jean de Fillets stick their heads out of the water or lava, then jump out, knocking Yoshi away if they touch him. They can be defeated with an egg or another object thrown at them.
