As the lights fade, a female narrator gives a brief welcome and mentions of the powers of imagination. A very faint musical note is heard, swelling and growing into a dramatic chord in the complete darkness. Once the chord strikes, two tall columns rise on stage left and right, with roving spotlights, until finally Tigger appears centre stage. He conducts various water fountain effects, until bringing up the giant water-mist screens, which, in conjunction with a few flares, fade into the famous Sorcerer's Apprentice scene from Fantasia.
From there, the falling stars of the Sorcerer's Apprentice scene morph into flowers, and after a brief interlude, into a jungle scene. Elephants, giraffes, monkeys, birds, ostriches, rhinos, crocodiles, and cheetahs begin to herd in the mountain. Neon animals make noise and dance around on the island while Rafiki and monkeys do a dance on floats traveling across the water. Simba and Nala from The Lion King romp together. Next, a large Bubble Montage takes place, where scenes and characters from major Disney and Non-Disney movies appear in floating bubbles. Scenes from The Lion King, The Jungle Book, Tarzan, Dumbo, Arthur, Snow White and the Seven Dwarfs, Thomas and Friends, Alice in Wonderland, Kim Possible, Hercules, Swan Princess, Peter Pan, SpongeBob Squarepants, American Dragon: Jake Long, Pinocchio, Fanboy and Chum Chum, Aladdin, Animaniacs, Oliver and Company, Little Bear, Franklin, Teen Titains, Power Rangers, Mulan, Avatar: The Last Airbender, Pokemon, Cinderella, Shrek, Madagascar, Lady and the Tramp, Fantasia, Bambi, Beauty and the Beast, and The Little Mermaid pop and float across the screen.
An animated Monstro next appears onscreen, accompanied by a heavy musical score as he crashes through the waters. The chaotic sea morphs into one of the opening scenes from Sonic Adventure 2: Battle, with the space colony ARK will impact the earth. The screens disappear, and the lights immediately darken.
A loud cannon blast erupts. Live characters re-enact scenes from the film, Sonic Adventure 2.where Sonic and Knuckles entered the room Amy and Tails were in but then they heard a rattle and suddenly Rouge came out of the blue. "You, you haven't give up yet?" Knuckles said. Rouge said that they are all doomed because the Space Colony Ark is heading towards Earth at a tremendous velocity. On T.V. everywhere, including the Ark, Gerald Robotnik is tied to a seat explaining how the Ark will crash into Earth and destroy it among the savage humans, with the power of all seven Chaos Emeralds.
Eggman comes in and Knuckles starts yelling at him, thinking that Eggman is behind all of this. But then Eggman gives Rouge his grandfather's diary and Rouge reads it out loud revealing that the professor went insane after his granddaughter Maria was killed. When the Space Colony ARK was shut down, Maria was killed in the process. Gerald went mad because he loved Maria so much. He wanted to curse all humans, so he made the Eclipse Cannon, and when having enough power (the 7 Chaos Emeralds) would be programmed to make ARK fall to Earth. It is revealed that Gerald made Shadow for good, to benefit man-kind but Space Colony ARK was destroyed, and as a result, so was project Ultimate Life Form A.K.A. Shadow. He was able to complete his research and finish Shadow, and he says that you may awaken it "if you wish to fill the world with destruction".
The gang have to stop the energy from the Chaos Emeralds to stop the Space Colony ARK from crashing with Earth. They then have a plan to stop the Chaos Emeralds with the Master Emerald. Amy finds Shadow and convinces him to help save the world. Shadow then has a flashback of Maria telling him the same, and launching him out of a shuttle down to Earth, so he wouldn't be destroyed on the ARK. He then takes off saying "I have to go now! I need to keep my promise to Maria...and you."
Sonic and Knuckles are seen at a shrine that looks somewhat like the Shrine of the Chaos Emeralds, with the Chaos Emeralds there. When Sonic and Knuckles try to get closer to the Shrine to stop the Chaos Emeralds with the Master Emerald, Gerald's voice is heard again, and a snake/lizard like beast is awakened. They realize that this is the prototype of the Ultimate Life Form, Shadow being the finished product. Shadow appears and defeats the Biolizard (prototype of the Ultimate Life Form), while Sonic and Knuckles get to the shrine and find a space for the Master Emerald. Knuckles does the chant to negate the power of the Chaos Emeralds, and the Biolizard Chaos Controls into outer space. They hear Eggman's voice saying that the Biolizard has fused with the Space Colony ARK and is keeping it on its crash course to Earth.
Space Colony ARK, is no longer being powered by the Chaos Emeralds, but now by the Finalhazard (Biolizard fused to the Eclipse Cannon). Sonic and Shadow use the Chaos Emeralds to transform into Super Sonic and Super Shadow, respectively. They fight the Finalhazard in outer space, and just as they are about to stop Space Colony ARK, when Maria's voice rings in Shadow's head again about giving people a chance to be happy. Both Sonic and Shadow use Chaos Control to warp the crashing space colony ARK back to its normal place, but Shadow's power was drained and he fell to Earth, realizing that he had fulfilled Maria's request in his "dying" moments.. The show then moves into classic dancing scenes with Princess Aurora and Prince Phillip, Cinderella and Prince Charming, Simba and Nala (in adult forms), Tiana and Naveen, Xiro and Kairel, Jake Long and Rose, Arthur Read and Francine Frensky, Tarzan and Jane, Hubie and Marina, Odette and Derek, and Princess Jasmine and Aladdin.Three small floats now arrive, with Belle and the Beast, Ariel and Prince Eric, and Snow Whit and her Prince each contained in their own float. As each float reaches the centre, the spotlight shines on it, with the accompanying signature melody from each movie — "Beauty and the Beast," "Part of Your World," and "Some Day My Prince Will Come", respectively.
The music takes on an ominous tone as Tigger's dream takes a turn for the worse. The Wicked Queen from Snow White and the Seven Dwarfs on stage, calling for her magic mirror — which appears onscreen in animated form. The mirror informs the Queen that the three princesses are fairer than she, and that "in Tigger's imagination, beauty and love will always survive." Angered by this, she concocts a spell amidst pyrotechnics and other special effects, and turns herself into a hag. Upon being told by the Magic Mirror that she now has the power to control Tigger's mind, she invokes some of the most infamous Disney villains:
- Ursula from The Little Mermaid
- Yzma from The Emperor's New Groove
- Shere Khan from The Jungle Book
- Hyenas from The Lion King
- Dagnino from El Arca
- Thrax from Osmosis Jones
- Judge Doom From Who Framed Roger Rabbit
- The Grand Duke of Owls from Rock-A-Doodle
The Grand Duke of Owls uses his owls to attack Tigger. After escaping from the owls, Tigger encounters The Grand Duke, who transforms into a tornado appearing on both the stage and the mist screens. Seeing a magic lamp, Tigger rubs it, assuming it will help him. Unfortunately, The Grand Duke of Owls calls upon Malefor (The Legend of Spyro: Dawn of the Dragon) and Chernabog (Fantasia) (whose appearance is accompanied with a composition of "Night on Bald Mountain" and "Hellfire").
On stage, Tigger encounters Maleficent, who transforms into a 40-foot-tall fire-breathing dragon that sets the waters ablaze. Guests as far as halfway back in the theater can feel the heat from the fire. Mickey, now in his Brave Little Tailor outfit, apppeared to save Tigger's dream and manages to create a wall of water around the island, smothering the flames and defeating the dragon. He destroys the villains using the power of his imagination and his sword (similar to The Sword in the Stone). Maleficent also dies as the water splashes with a large firework bang. All is quiet, until Tinker Bell appears and flies to restore the mountain. Magical stars sparkle in the mountain as the Steamboat Willie River Boat approaches. Then a spark of pyrotechnics ignite from the riverboat, revealing Mickey controlling the boat.
As it glides past the audience, various Disney and Non-Disney characters appear aboard the River Boat, dancing with golden streamers. A celebratory atmosphere prevails amid a flurry of fireworks. With another flash of pyrotechnics, Mickey appears atop the highest point of the mountain as the Sorcerers Apprentice as fireworks, fire, and water light up the stage. As the finale concludes, Mickey disappears from the top of the mountain with another spark of pyrotechnics, a small explosion in the main stage and simultaneously reappears in his shiny tuxedo suit. A small applause from the crowd and Mickey says, "Some imagination, huh? Ha ha!" Pyrotechnics shoot out of the main stage and barges on the moat, he vanishes one last time to the final notes of the music while a cone of lights and searchlights bright up the stage for a few seconds. And for the last note of the song they use one big bolt of white pyrotechnics. Then the lights return to normal and the show is concluded.
