K. Rool's Kingdom
From the Super Mario Wiki, the Mario encyclopedia
K. Rool's Kingdom is the final boss level of the game Donkey Kong Land and is the final level in Big Ape City. In this level, the player must beat King K. Rool. It is similar to the level Gang-Plank Galleon in Donkey Kong Country.
King K. Rool throws his crown at the player and then runs in the direction he is facing. While he is running, the player can damage him by jumping on his head. After six hits, he will run back and forth while jumping and bellyflopping on the player when he is near them. After he jumps six times, he will continue his previous cycle of running and throwing his crown, though at a faster speed. After six more hits, he falls off the level. The word "Congratulations" is shown on the screen and the credits roll.
