Chomp Sharks are giant Chain Chomps from Super Mario World 2: Yoshi's Island that are invincible and will kill Yoshi if he tries to backtrack. In the second to last stage, "KEEP MOVING!!!!", this stage earns its name because there are so many Chomp Sharks that it makes it impossible to backtrack. They also appear in Marching Milde's Fort as their first course.
