Cheep Chomp

Cheep-Chomps are Cheep-Cheeps that are bigger than usual found in underwater levels in New Super Mario Bros. and New Super Mario Bros. Wii.

These Cheep-Cheeps are purple with a green backfin and have enormous mouths. In New Super Mario Bros., if Mario or Luigi swim too close to the Cheep-Chomp, it opens its mouth and try to eat the adventurer. The giant fish often follows the character around the screen while attempting to devour them. Success on their part causes the player to lose a life, regardless of the player's condition. They can be defeated, like all other fish, with a Fireball or being smashed by Mega Mario/Luigi. Only four appear in the entire game, all of them appearing in the same level: World 3-1.

In New Super Mario Bros. Wii, only two Cheep-Chomps appear: Once in a bonus area in 4-4, and again in a bonus area of 9-2. A Fireball or Starman takes the big fish down, but it is invincible to ice balls from Ice Mario. Two changes are made from New Super Mario Bros.: it is slightly bigger, and defeating it releases three 1-Up Mushrooms.
