Frogoon

Frogoons are creatures in Donkey Kong Country Returns and Donkey Kong Country Returns 3D. They are green frog foes who follow the bidding of the Tiki Tak Tribe. Frogoons hinder the Kongs with attacks that involve jumping and down in place. They can jump higher than usual by inflating their bodies. Donkey Kong can easily subdue Frogoons by jumping on top of them, causing them to deflate. Frogoons frequently appear close to each other in groups allowing Donkey Kong to defeat all of them in one fell swoop. A yellow sub-species called Hopgoon also appear.

In Mario Kart 7, Frogoons appear as obstacles on DK Jungle. Here, they don't inflate at all, and only jump across the road, thus acting like Hopgoons. They return in Mario Kart 8 and Mario Kart 8 Deluxe as the 3DS DK Jungle course returns as a retro course.

Trivia

 * If the player watches very closely, they will see a small fly that Frogoons try to eat.
