In 2021, a 15-second clip of early animation tests for the game dating back to 2006-2007 was discovered on the website of animator Michael Daubert, who worked on animations for an early iteration of the game, but went uncredited in the final release as everything in the test footage was scrapped. These tests showcase a completely different art style from the final game and unused gameplay elements, with Mickey shooting ink out of his body to quickly surf around, and jumping and slamming the ground to summon a tidal wave of ink to attack large Blotling enemies. This tidal wave attack also causes Mickey to lose all of his colors, turn white and become exhausted, suggesting that the known early idea of ink/paint/thinner usage changing his physical appearance was going to involve a stamina meter tied to his attacks. Mickey's early design was more stylized compared to his traditional appearance in the final game, featuring a prominently tall forehead, a lanky, stretched body, no visible mouth, and crooked oval ears. This early design would live on through an emblem used in promotional materials and as a recurring icon throughout the final game, with the inky black outline of the early design's head forming an "M".
