Gold Chomp

Gold Chomps are special Chomps in Super Mario Galaxy and Super Mario Galaxy 2.

The only Gold Chomp in Super Mario Galaxy appears in the Gusty Garden Galaxy, where it plays a prominent role in the mission The Golden Chomp. It contains a Power Star inside, but Mario is unable to break it open without the use of a Rainbow Star, which can be obtained after collecting a series of ? Coins. This power-up allows the player to destroy the Chomp, revealing the Power Star.

In Super Mario Galaxy 2, Gold Chomps appear in the Chompworks Galaxy's first mission, Where the Chomps Are Made of Gold. Here, Mario must lead a Gold Chomp from the end of an area all the way back to the front of the area. However, it takes a set route and Mario must alter the area slightly to allow the Gold Chomp to roll to the front of the area and into a hole, where it will break and reveal the Power Star. They reappear in the Chompworks Galaxy's Prankster Comet mission titled Cosmic Clones in the Chompworks, where they serve the same role as before.

Trivia

 * In Super Mario Sunshine, while visiting Pianta Village during the fourth episode in "Chain Chomp's Bath", if Mario drags the Chain Chomp into the tub, it will turn golden and a Shine Sprite will appear from its head.
