Eventually, the Shark Chomp chases Yoshi to a platform it cannot eat and breaks its teeth, causing it to tear up in pain and fall off the screen. Their appearances in certain levels make backtracking impossible, as they are almost invulnerable and will often eat anything on which Yoshi can land. These giant Chomps relentlessly chase after Yoshi, gnashing through anything in their way. Shark Chomps (also named Bow Wow or Giant Chomp-Chomp ) are introduced as one of the three varieties of 'Chomps' in Super Mario World 2: Yoshi's Island, where they appear in Marching Milde's Fort and KEEP MOVING!!!! In the former level, the Shark Chomp appears right after a group of Incoming Chomps.
