Cheep Chomp

Cheep-Chomps are enormous Cheep-Cheeps found in underwater levels in New Super Mario Bros.

These Cheep-Cheeps are purple with a green backfin and have enormous mouths. If Mario or Luigi swim too close the the Cheep-Chomp, it will open its mouth and try to eat the adventurer. Success causes the player to lose a life.

In this respect, the Cheep-Chomp is a lot like the Boss Bass from Super Mario Bros. 3.
