Hopgoon

Hopgoons are enemies that appears in Donkey Kong Country Returns. They are a yellow and black variant of Frogoon and unlike their weaker, stationary relative, Hopgoons hop around the level and can even jump over gaps thus making them a major inconvenience when ever they appear, however they can easily be defeated by any means. It is worth noting that unlike Frogoons, these enemies will only be stunned with Diddy Kong's peanuts, while the former immediately dies upon getting hit.

Trivia

 * These foes bear great resemblance to the "Yellow-banded poison dart frog".
 * One of only a few similarities to the two frog enemies in said game are that they both balloon up, and float off screen after being defeated.
