Frame Chomp

Frame Chomps are enemies that first and only appeared in Yoshi's Woolly World, having a more different look than normal Chain Chomps. They won't attack if Yoshi is near them, but they will follow and attempt to bite him. Yoshi can turn them to Chomp Rocks if he hits them with a Yarn Ball, which will cause the yarn to envelop on the Frame Chomp in the depicted color, turning it solid and incapable of movement by itself. They can be returned from Chomp Rock form to normal Frame Chomps if Yoshi unties the ribbon on top of the Chomp Rocks with his tongue.
