The game over screen of Mickey Mania and its PlayStation port Mickey's Wild Adventure, where Mickey lies down on the ground, holding a lily with X's in his eyes, is the only time Mickey Mouse has ever been shown as dead on-screen in an official Disney product.

If one punches or shakes a Sega Genesis while Sonic 3D Blast is playing, they will access the level select screen. This was not an intentional Easter egg, but rather the result of a loophole made to speed up Sega's tedious quality assurance pipeline by having the level select appear as a failsafe when the game crashes, meaning that Sega testers would simply believe they had unlocked a secret - this trick had previously been used in the development of Mickey Mania: The Timeless Adventures of Mickey Mouse.
