Donkey Kong: Coconut Crackers (cancelled Game Boy Advance game; 2002)
In the early 2000s, Rare was developing several games for Nintendo's new Game Boy Advance and GameCube systems, many of which starred Nintendo-owned characters. One such game was Donkey Kong: Coconut Crackers.
Donkey Kong: Coconut Crackers was to be a puzzle game with an isometric view. Donkey Kong would drop coconuts filled with paint, and the player must use this paint to make squares and rectangles. Kremlings occasionally show up and hinder the player's progress. A playable demo was made, and demo videos were released.
In September of 2002, Microsoft bought Rare Ltd., and because Microsoft had just recently entered the video game industry with their Xbox, Rare cancelled and/or reworked many of the games they were developing. Donkey Kong: Coconut Crackers was cancelled, and the idea was reworked into a Game Boy Advance game called It's Mr. Pants, featuring Rare's unofficial mascot Mr. Pants, which was released on December 7, 2004.
To this day, the playable demo of Donkey Kong: Coconut Crackers has not yet been dumped and leaked.
