Instructions
Enter a stage and look for the "Koin" Kremling. (He has a metal bucket on his head and a shield with the letters "DK" on it.) One Koin Kremling can be found for each stage in the game.
Defeat a Koin Kremling by finding a "Steel Keg" and throwing it behind him so that it hits a wall and strikes him in the back. A few Koin Kremlings must be defeated with the help of a "Bazuka" Kremling. Bazuka Kremlings occasionally fire Steel Kegs from their bazookas. You can take advantage of this by luring a Bazuka Kremling to the area of a Koin Kremling and having it defeat him for you.
Defeat K. Rool at the stage "Knautilus" to get the last DK Coin. This is the only DK Coin that isn't received by defeating a Koin Kremling.
