Donkey Kong Country
In Donkey Kong Country, Chomps Jrs. appear in all four underwater levels, Coral Capers, Clam City, Croctopus Chase, and Poison Pond. Just like their larger counterpart, Chomps Jrs. attack either Donkey Kong or Diddy Kong by swimming into them. They move considerably faster than Chomps, at the cost of being smaller and easier to avoid. Like the other underwater enemies, Chomps Jrs. cannot be defeated by the Kongs alone; they can only be defeated if they are stabbed by Enguarde.
Chomps Jr. appears in a short segment of the ending credits in Donkey Kong's Treehouse, where it chases a Squidge off-screen, possibly trying to eat it. It then swims back on-screen, fleeing from a group of four angry Squidges.
In the Game Boy Advance remake, Chomps Jrs. appear in the Funky's Fishing mini-game. In the main game, Chomps Jrs. are the main feature of Vine Valley's challenge, where the Kongs must reel in 15 Chomps Jrs. within the time limit.
Donkey Kong Land
Despite Chomps Jr. themselves not being present in Donkey Kong Land, regular Chomps in this game are reskinned to look like Chomps Jr. This is traced from an official Donkey Kong Land guide book from Japan, which lists the regular Chomps as an enemy in the game instead of Chomps Jr.
