Silver Chomps are a new species of Chain Chomps appearing in Super Mario Galaxy 2. They work just like the other Chain Chomps in the game; however, these ones seem to follow their target, making them more or less easier to defeat or avoid. Mario first encounters one on his way through the Rolling Masterpiece Galaxy as the boss of Silver Chomp Grudge Match, and later encounters another in the Slipsand Galaxy as an obstacle that must be avoided in Sailing the Sandy Seas and later four at the end of his journey through the Battle Belt Galaxy as the boss of Mini Planet Mega Run. Silver Chomps are invulnerable to Mario's attacks unless he uses a rainbow star to defeat them or a bouncy plant or shoves them off the edge with a durable object such as a Star Ball, as the aforementioned Silver Chomp boss in the Rolling Masterpiece Galaxy proves. Silver Chomps have red pupils that roll around in their eyes.
