Instructions
Get to the end of the "Gorilla Glacier" world, then defeat the world's boss, Gnawty the Beaver, by jumping on him. Make sure to avoid his jumps across the screen by staying under him. After five hits, Gnawty will be defeated.
Navigate through the "Kremroc Industry Inc." world, and defeat the large canister boss by simply defeating all of the enemies that come out of it. Do not directly touch the boss. Once all the boss' available enemies have been defeated, it will self-destruct.
Get to the end of the "Chimp Cavern" world, and defeat Necky's father by jumping on him when he is near the ground. Avoid the nuts that fall from the ceiling while you do so. After five hits, Necky will fall and the final boss' level will become available.
Defeat the first form of King K. Rool by hitting him on the head every time he throws his crown at you. Between crown throws, simply avoid everything he does and any other objects in the room. After hitting him nine times, he will revert to his second form.
Defeat King K. Rool's second form by making use of Diddy Kong, rather than Donkey Kong. Hit him after every crown throw, while dodging his body. Since you are using Diddy Kong, who is smaller, K. Rool will have a harder time hitting you. You must hit him three times while in this form to win the game.
