After many decades of real-world fame following the accident, Mickey has completely forgotten the incident until the Shadow Blot enters his home through the mirror and abducts him into the ruined forgotten world, now named by this time as the Wasteland. Oswald all the while had his will and his mind twisted from years of hiding and his jealousy of Mickey's rise to fame, unaware the enigmatic Mad Doctor and the Blot formulate a plan to destroy Mickey and extract his heart, which they plan to use to escape the ruined world, as all Wasteland Toons are forgotten and thus no longer have hearts of their own. During his journey through the Wasteland, Mickey is guided by Gremlin Gus and becomes armed with Yen Sid's brush. Mickey uses the brush to restore the Wasteland in order to atone for his destruction and win a frustrated Oswald's trust.
