This 25-minute musical, which casts Mickey Mouse in his classic role of the Sorcerer's Apprentice from Fantasia, features songs from half a dozen Disney animated films. The show was arranged by Timothy Williams.
The story begins with Mickey once again in the studio of Yen Sid, as a team of mapmakers puts the finishing touches on an enormous map using giant paintbrushes. Trouble ensues when the mapmakers quit for the day, leaving a curious Mickey alone in the studio with a nearly complete map capable of taking dreamers to any place imaginable. Before long, a paintbrush-wielding Mickey is absorbed into the world of the animated painterly map (an ingeniously disguised LED screen spanning the width of the stage, along with a trapdoor to initiate the shrinking effects). His nemesis throughout the story is an amusing and stubbornly unfinished portion of the map named Spot.
From here, a series of choreographed set pieces starring a succession of Disney characters leap from itinerary stops made during Mickey's journey through the magic map. After Mickey paints his way out of the map, the show concludes with a pair of big production numbers set in Hawaii and New Orleans.
In the end, Mickey realizes his mentor has been watching over him the entire time, when the adversarial Spot is revealed as the pupil of Yen Sid's eye.
Yen Sid explains to Mickey that "(The map shall) never be completed, as long as there is imagination left in the world". This a reference to what Walt Disney said about Disneyland: "Disneyland will never be completed. It will continue to grow as long as there is imagination left in the world."
This is the second Disney parks stage show where three different Disney characters sing the songs of hope and yearning together, the first is Disneyland's former stage show, "Animazment - The Musical", and the third is Hong Kong Disneyland's current stage show, "Mickey and the Wondrous Book".
