In 2021, a 15-second clip of beta animations for the game dating back to 2006-2007 was discovered on the website of animator Michael Daubert, a former employee of the outsourcing studio The Animation Farm who produced animations for an internal pitch of an early iteration of the game. 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".

In 2024, an extended pitch trailer for this version of the game using some of the same animation footage was posted online by Thomas Heimann, another former employee of The Animation Farm. The pitch for this version of the game proposed a 2008 release date and outlined possible gameplay mechanics, an early version of the story, and early character designs for Mickey, the Phantom Blot, and the Blotlings. A model sheet for Oswald the Lucky Rabbit with character designs dating back to his initial usage in the 1920s-30s was also teased during the trailer, but he does not appear in it.
