Green Chomp
Shroom Chomps[citation needed] are a green variant of Chomp that appear in Donkey Kong Country Returns and Donkey Kong Country Returns 3D. Shroom Chomps first appear in the level Longshot Launch, along with the other Chomps.
Shroom Chomps constantly open and close their mouths. By opening their mouth, this reveals their tongue which is shaped like a mushroom. The Kongs can safely jump on their tongue, although Shroom Chomps immediately close their mouth if they do so. The Kongs take damage if they hit a Shroom Chomp while its mouth is closed.
If the Kongs jump on it but land on the inside of its mouth instead of the tongue, they will be eaten by it and have to shake the controller (press 
or 
repeatedly in the 3DS version) to force it to spit them out. If the Kongs fail to do so fast enough or in a certain amount of time, the Shroom Chomp will forcefully launch them into the air and the Kongs will lose a heart.
