Diddy Kong Pilot was intended to be the next game in the Diddy Kong Racing line, to be released for the Game Boy Advance. It was presumably the sequel to Diddy Kong Racing, due to the screenshots of flight gameplay bing very similar to the previous game, though exclusively flying likely to the Game Boy Advance's limitations. The character cast returns with Diddy Kong from the previous game, and was to include Donkey, Dixie, Cranky, and an unnamed Kong know as Redneck Kong, who was later removed and replaced by Candy Kong. Other Kremling characters in the game would be Krunch the Kremling and K. Rool.

The game was also going to have a motion tilt sensor, much like the game Yoshi Topsy-Turvy. As the game was not far in development, only the title screen has music and most of the courses are unfinished. However, there exist six unused sound tracks in the ROM. Also, some courses are not entirely functional. The modes in the game include a Racing mode, a Story mode, a Dogfight mode, a Battles mode, and a Clock Race mode. In the Options menu, there is only the option of whether to use tilt controls or not. The story selection screen has Back to the Light, K. Rool's Gold, and King of Kongs options. Each character would also feature his/her story to play through.
