A long time ago, the sorcerer Yen Sid used a magic paintbrush to create a world for Disney's forgotten characters. This was held in an intricate model on a table and was accessible through a mirror. One day, Mickey is taking a nap when his mirror makes an odd noise, awakening him. He climbs onto his dresser and pokes it to see that he can go through it. Mickey, who finds himself inside Yen Sid's study, sees the model and waits until Yen Sid is gone before going back to take another look at it. After grabbing Yen Sid's magic paintbrush, Mickey attempts to create a statue of himself in the world but instead creates the Blot. He attempts to erase it but ends up spilling Paint on the model. He attempts to clean it up in a haste but just spills even more Paint and Thinner, destroying and twisting the world. He manages to escape without Yen Sid knowing and returns to his world where he went on to live years of success and fame.
