The Flying Krock

The Flying Krock is the name of the gunship 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-look 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 they fly 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 hitting Donkey Kong with his own cannon, 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 was on the left side than the right and the bridge was gone (probably because this game featured the banana peel trails a la the original Donkey Kong Country.)
 * 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.
