Chomp Rocks are round stones that look like Chomps in Super Mario World 2: Yoshi's Island, its remake, Yoshi's Island DS and Yoshi's New Island. They appear in many levels and are used for moving through soft rock, and reaching high areas. In some levels they are an obstacle, such as when they need to be rolled off a thin pillar to reach a key. Some Sluggers hit these back and forth. In the Yoshi's Island games, Yoshi can push Chomp Rocks forward or jump on top of them to roll them in any direction. He can use Chomp Rocks to crush most enemies, even otherwise-invulnerable foes, such as a Tap-Tap.

The difference between the gray and brown Chomp Rocks in the original game is that the gray ones will go back to their starting point if the player leaves the screen, and the brown ones will not. However, neither color goes back in the sequel, except for the one in the Island Museum's Land Enemy section - which happens to be brown.

Chomp Rocks reappear in Yoshi's Woolly World, acting the same as in previous Yoshi games.[1] In this game, they are amigurumi crochet spheres that come in many different color variations with white buttons for eyes. Frame Chomps can be turned into a Chomp Rock if Yoshi throws a yarn ball at one. The color of the Chomp Rock is determined by the color of yarn used.

Chomp Rocks made a cameo appearance in Paper Mario. They can be found in the background of Dry Dry Ruins and resemble the living Stone Chomps, which are actually based off of Chain Chomps. They are also seen outside the Dry Dry Ruins, on decorative pedestals surrounding the outside. Paper Mario's Chomp Rocks have slightly gaping mouths.

Two Chomp Rocks appear in Paper Mario: The Thousand-Year Door. In this incarnation, the rocks are hollow and have open mouths. They sit on top of Warp Pipes, preventing entry. Mario can destroy the rocks by throwing Admiral Bobbery into the gaping maws of the rocks. When Bobbery explodes, the rock is destroyed.

Brown Chomp Rocks make an appearance in Mario & Luigi: Partners in Time, where the Yoshis are needed to move them on two occasions to open up new paths in Yoob's Belly. Five Yoshis can also use a Chomp Rock to lower Sunnycide's defense after the Bros. free them from Yoob eggs.

In the Club Nintendo comic "Mario's Picross", Mario gets arrested inside of a pyramid. He comes across a treasure chamber with a chest inside. When trying to pick up the treasure chest, a Chomp Rock is released through a trap door and starts rolling towards Mario. He escapes from the rock by jumping into a lorry and moving away.
