Hopgoon

Hopgoons are enemies appearing in the game Donkey Kong Country Returns and Donkey Kong Country Returns 3D. They are yellow frogs and look exactly like Frogoons, the only difference being than Hopgoons are yellow in color. However, instead of inflating themselves in one place, Hopgoons move around the level and can hop over gaps. Donkey Kong and Diddy Kong can easily defeat them with a jump, by rolling into them, with Rambi, or with a barrel.
