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 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.

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

An incoming 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 incoming Chomps in Super Mario Galaxy.

In the upcoming game Super Mario Galaxy 2 a strange looking Chomp Head appears for a brief moment in the trailer. This Chomp head looks different than other Chomp Heads. The Chomp Head is silver and a small golden circle holding the eyes appear. Another note is that the pupil is red. It is also much larger than the Chomp Heads in the prequel.

Trivia

 * An Incoming Chomp made a cameo appearance in Paper Mario, along with many other Chomp-related things. The outline of an Incoming 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.
