The Flying Krock

The Flying Krock is the name of the airship used by Kaptain K. Rool in Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2. It is also the name of the final area of the game where Donkey Kong is held captive by the Kremling Krew. The Flying Krock resembles a giant mechanical crocodile-shaped helicopter.

In the Game Boy Advance remake, a short cutscene at the beginning of a new game shows Kaptain K. Rool and the Kremling Krew using The Flying Krock to kidnap Donkey Kong and flying away to the top of Crocodile Isle. Diddy and Dixie Kong later find out that Donkey Kong was missing and they go on their own journey to save Donkey Kong from the Kremling Krew.

Levels
The Flying Krock only has a level and a boss level, "Screech's Sprint" and "K. Rool Duel".

Screech's Sprint
In "Screech's Sprint", Diddy and Dixie along with Squawks has to face Kaptain K. Rool's pet parrot, Screech in a race through a bramble maze on reaching the Star Barrel. Squawks must avoid Zingers and red ones later in the race, making the race difficult. Squawks and Screech fly throughout the level. After Squawks wins, Diddy and Dixie go to K. Rool Duel where they battle against Kaptain K. Rool as the name implies.

K. Rool Duel
K. Rool Duel is the boss level of this world. When the Kongs enter the boss level for the first time, they see Kaptain K. Rool in the process of torturing Donkey Kong with his blunderbuss, before engaging the tyrannical crocodile in a battle. The Kongs at first seemed outmatched by K. Rool's super enhanced blunderbuss but eventually managed to defeat him and sent him flying into the swampy waters of his island.

Trivia

 * In the Game Boy Advance remake of Donkey Kong Country 2: Diddy's Kong Quest, the Flying Krock itself is directly above K. Rool's Keep, rather than in front of it, and the ladder goes straight up. Additionally, the world's Kong Kollege is now on the top tower of the Keep, instead of inside the bramble patch, like Funky's Flights II.
 * In Donkey Kong 64, K. Rool had the King Kruiser II, an airship that resembles a smaller version of The Flying Krock. Two other airships called the K. Kruizer III and the King Kruiser IV appear in DK: King of Swing and DK: Jungle Climber, respectively.
 * depicts the Flying Krock as a simple blimp in the shape of a cartoonish crocodilian head. It also refers to it as being a sky-themed world, suggesting that originally it was intended to have more levels than in the final.
