Chain Chomp (unchained)

Not to be confused with Chain Chomp. 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 everything that is below them (strangely, Yoshi doesn't lose Baby Mario when hit by one of these enormous monsters). 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 appears in Super Mario Galaxy and roll straight off the planetoid, just like Piranhabons from Super Mario Sunshine. They come in two different sizes and are unaware of their surroundings but if Mario is to step in front of the Chomp, he will surely be knocked over and hurt. Chomp Pups come out of dog houses, found only in the Dreadnought Galaxy.

Chomps are very similar to Chomp Sharks from Yoshi's Island and Chomps from Yoshi's Story.

A Chomp also appears as a stage hazard in Chain Chomp Roulette in Mario Kart Wii. It rolls around in the mid section of the roulette wheel squashing racers who it runs into, or vice-versa. It looks exactly the same as the Chomps in Super Mario Galaxy. Some of them did make appearances in the Mario Kart Wii Competitions.

In Super Mario Galaxy 2, Chomps reappear along with a new Incoming Chomp known as the Silver Chomp. Chomps first appear in the Flip-Swap Galaxy as the common obstacle there. They later reappear in the Chompworks Galaxy, where they make their most prominent appearance.

Trivia

 * A Chomp made a cameo appearance in Paper Mario, along with many other Chomp-related things. The outline of a Chomp appeared whenever Tutankoopa used his crushing spell; most of the time it would fall and crush Mario and his partner, but it would occasionally crush Tutankoopa himself, making the pharaoh more vulnerable to attack.
