Diddy Kong Pilot is the name of a canceled Game Boy Advance racing title starring Diddy Kong and other Donkey Kong characters racing against each other in planes. This iteration was entirely redone from the original version, before finally being redesigned into Banjo-Pilot in 2005.Team Krem consists of four of the Kremlings: Kritter, Klap Trap, Klump, and K. Rool. The whole team is unlocked when the Kongs win against them in every cup and dogfight challenge. After the player beats every cup and wins against all four Kongs in dogfights while playing as a Kremling, the title screen and the selection menus are reskinned from the original jungle theme to have a Kremling theme. The title screen reads Kremling Pilot, and it takes place in a ruins area with lava. The options and selection menus are replaced with a scaly red and yellow background. Before starting a cup as a Kremling, Cranky talks in a disgruntled manner toward them.
