K. Kruizer III
The K. Kruizer III is an airship owned by King K. Rool in DK: King of Swing, the third in a long line of aircrafts built by him and the Kremling Krew. It also serves as the fifth and final world, and the boss is King K. Rool. Donkey Kong (or Diddy Kong in Diddy Mode) can access the world after they defeat Sassy Squatch in the Ice World.
The K. Kruizer III was preceded by the King Kruiser II from Donkey Kong 64, and the original Flying Krock from Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. The K. Kruizer III is later succeeded by the King Kruiser IV in DK: Jungle Climber.
The K. Kruizer III is a large aircraft, with heavy artillery on the outside and spike traps on the inside. The design and colors are modeled after King K. Rool. The only way for Donkey Kong to get on the ship itself is by using a Booster Barrel in the first level, then in the second level, he must avoid the artillery. By the third level, Donkey Kong enters the hull of the ship, which is filled with spike traps. The fourth level takes place in the engine of the ship, which has cannons and fast moving pegs. The final battle against K. Rool takes place at the top of the ship.
After defeating K. Rool, Donkey Kong jumps into a flying carrier, with all the medals in a large barrel. He gets out of the K. Kruizer III, and parts of the airship explode before the entire K. Kruizer III falls from the sky.
Getting a bronze, silver, and gold medal from the respective levels unlocks Climbing Race 4 in Jungle Jam mode.
