Donkey Kong Country 2: Diddy's Kong Quest

Donkey Kong Country 2: Diddy's Kong Quest was the rescuing of Donkey Kong from Kaptain K. Rool.

History
Donkey Kong was relaxing on the beaches of Donkey Kong Island, despite Cranky Kong nagging at him for his laziness. Donkey Kong falls asleep, which allows the Kremlins to capture him inside their ship. The Kremlins leave behind a ransom note for the other Kongs; Donkey Kong for the banana hoard. In response, Diddy Kong and Dixie Kong decide to rescue Donkey Kong themselves.

Their journey through Crocodile Isle is aided thanks to Cranky Kong, Wrinkly Kong, Swanky Kong, and Funky Kong.

The two Kongs finally encounter Kaptain K. Rool, who they then fight onboard his airship. Donkey Kong is freed from captivity, and he uppercuts K. Rool outside his airship. K. Rool recovers, however, and retreats into the Lost World area of the Crocodile Isle.

With enough Kremkoins for Bubba to let the Kongs through, Diddy and Dixie Kong have their second encounter with K. Rool. With enough finesse to dodge all his cannonballs, K. Rool's malfunctioning gun shoots him inside the Krocodile Kore, destroying all of Crocodile Isle.
