Koin

Koins are Kremlings encountered in every level of Donkey Kong Country 3: Dixie Kong's Double Trouble. Koins wear buckets on their head and carry a shield which has a DK Coin attached to it. If the Kongs approach a Koin he will simply bash them away, if they attempt to jump on him he will simply raise his shield and block them. The only way Dixie or Kiddy Kong could defeat a Koin is by throwing a Steel Keg over them, the Steel Keg will then rebound off a wall (sometimes the Kongs must find another way to defeat Koin using the Steel Keg) and hit Koin in the back thus defeating him and giving Dixie and Diddy a DK Coin reward.

A purple-ish version of Koin called Koindozer is encountered in the level "Koindozer Klamber". Koindozers are much more aggressive than their green brethren chasing the Kongs and attempting to bash them into pits.

Trivia

 * The name Koin is derived from the words, Coin and Kremling.
