Nintendo has reused Grant Kirkhope's (the composer of the music for Donkey Kong 64 as well as DK's voice actor) voice clips for DK's voice in other games such as Mario Golf: Toadstool Tour, Mario Kart: Double Dash!!, Mario vs. Donkey Kong, the GBA remake of Donkey Kong Country, & even in the E3 demo of Donkey Kong Jungle Beat.

There is an unreleased Donkey Kong music game called Donkey Kong no Ongaku Asobi (translated to Donkey Kong's Fun with Music). It would have been on the NES and would have followed Donkey Kong Jr. Maths as a series of Donkey Kong edutainment games.

With the success of Donkey Kong Country, Nintendo gave Rare permission for a sequel on the Virtual Boy. This happened just after the launch of the Virtual Boy and was only in the early planning stages for a matter of weeks before it was cancelled due to lack of sales of the Virtual Boy console.

Swanky and Candy are the only two Kongs yet to be playable, though Candy was going to be a playable character in the cancelled Diddy Kong Pilot a few weeks after Redneck Kong was scrapped from the game. They both are members of the "Bonus Bonanza" in the Game Boy Advance remake of Donkey Kong Country 2.

Shigeru Miyamoto has stated the name "Donkey Kong" came from him confusing the word "donkey" with the word "ass", thinking it meant something stupid. He assumed an American audience would think "Donkey Kong" meant "big stupid ape". Nintendo laugned when he suggested the name, but it ultimately stuck.
