This is a list of pre-release and unused content for the game Donkey Kong Country 3: Dixie Kong's Double Trouble!.
E3 1996 trailer
The game's E3 1996 trailer (whose footage was later featured in a Brazillian commercial) features a few differences from the final build .
A screenshot on the back cover shows that the Bazza enemies were originally eel-like creatures instead of the barracuda-like fish of the final game.
There are unused sprites in the game. They are sprites of Kracka (which were eventually used in the Game Boy Advance version) and unused sprites of Kopter (some of which were eventually used in Donkey Kong Land III).
Early Karbine Design
Karbine originally wasn't intended to be an owl; instead, the original design for the enemy depicted a robotic ape with a propeller on the tailbone area. This design can be see on page 33 of the 89th issue of Nintendo Power.
