Koin

Koins are Kremlings encountered in every level of the games Donkey Kong Country 3: Dixie Kong's Double Trouble! and Donkey Kong Land III. Koins wear buckets on their head and carry a shield which has a DK Coin attached to it. The name Koin derives from Donkey Kong Country developers spelling many words that start with "C" with a "K," like many other Kremling names. According to the game's credits, Koins belong to the "Kremling Kreeps" enemy class.

Dixie Kong and Kiddy Kong can defeat a Koin by using a Steel Keg; oftentimes, they have to throw the Steel Keg over him, which will then rebound off a wall and hit Koin in the back, defeating him and giving Dixie and Kiddy a DK Coin. If the Kongs themselves approach a Koin from the front, he will knock them away; if they attempt to jump on him, he will raise his shield and block the jump. Most of the time, Koins are found near the beginning or the end of the level. After the DK Coin is collected, a Koin will use a trash can lid as a shield.

Some Koins can only be defeated with the assistance of a Kremling enemy named Bazuka. In some levels, the Steel Keg required to defeat Koin is obtained by bringing an Animal Friend past the No Animal Sign. In these cases, the Kongs only get one chance to defeat Koin; if they fail, they must replay the entire level to get another chance.

Multiple Koins with a dark pink tint, dubbed the Koindozer Klan, are 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.

In Donkey Kong Land III, Koins are absent in underwater levels since they do not have a separate cave area like those in Donkey Kong Country 3. Instead, the DK Coin is hidden in the level much like they were in Donkey Kong Country 2 and Donkey Kong Land 2.

In the Game Boy Advance version of Donkey Kong Country 3: Dixie Kong's Double Trouble!, it is possible to defeat Koin with a regular or TNT Barrel, which is not possible to do in the original SNES version. However, this can only be done in certain levels.
