Chain Chomp (unchained)

Incoming Chomps are chainless Chain Chomps with a great jumping ability found in Super Mario World 2: Yoshi's Island and its sequel, Yoshi's Island DS. They are much bigger than normal Chain Chomps, setting the standard for their huge sizes. They jump from the background hills and destroy the ground that they land on. They seem to be unlimited in number on the background hill or they come back to the same hill after jumping. They only appear in certain levels, when a sign with one of them on it appears. A similar enemy will also appear in Super Mario Galaxy and roll straight off the planetoid, just like Piranha Heads from Super Mario Sunshine. They are unaware of their surroundings but if Mario is to step in front of the Chomp, he will surely be knocked over and hurt.

Trivia

 * In Super Mario Advance 3: Yoshi's Island, the distant hills roamed by Incoming Chomps included Shy Guys and Vases; these hills appear to have been modeled after Super Mario Bros. 2.
 * Interestingly, the aforementioned hills were much simpler (yet more colorful) in the original Super Mario World 2: Yoshi's Island, where they housed only Incoming Chomps.
