Diddy Kong Pilot

Diddy Kong Pilot was a planned sequel to Diddy Kong Racing, but with flying as the only means of transport. However, it ended up cancelled. After its cancellation and after Rare was acquired by Microsoft, Diddy Kong Pilot was converted into the game Banjo-Pilot in 2005. Characters confirmed to appear in the game were Krunch, Dixie Kong, Diddy Kong, Donkey Kong, King K. Rool, Cranky Kong and a character tentatively called "Redneck Kong". There is a screenshot showing a rocket boost in it which revealed that rocket boosts were probably going to be an item in the game.

It is unknown if all the characters featured in Diddy Kong Racing would return in Diddy Kong Pilot. Diddy Kong Pilot would have been Rare's first game on the Game Boy Advance if it had not been cancelled.
