List of Donkey Kong Jungle Beat pre-release and unused content

This is a list of pre-release and unused content for the game Donkey Kong Jungle Beat.

E3 2004
During E3 2004, a playable demo of Donkey Kong Jungle Beat was on display and it differs from the final version in many ways. For example, the Helper Monkeys, rather than being gibbons, were regular brown monkeys. Also, Dread Kong did not exist in this early build. Instead, it was an unnamed Donkey Kong clone with gray fur, no tie and glowing red pupils. Also, whenever Donkey Kong banged his chest after defeating a boss, he would make a loud, high-pitched squealing noise, rather than the Tarzan-esque noise he makes in the final. In order to begin a boss battle, the player had to move Donkey Kong forward slightly, as opposed to the final game, where the match would automatically begin after it's finished loading. Jungle Beat has also gone through graphical changes, as well as changes to the energy meter, and there was also a combo meter that wasn't seen in the final game. Additionally, the E3 demo featured certain areas that weren't seen in any stage of the final release. The logo also looked slightly different. In addition, with the exception of DK's squeal, all his voices were recycled from Donkey Kong 64.
