The narrator, introducing itself as "the voice of time," begins telling the story of Mythica. Long ago, humans and mythical creatures coexisted in a harmonious beat. However, the humans became increasingly argumentative and violent, and in the resulting chaos, the beat vanished and the creatures had no choice but to retreat to the depths of the sea, never seen again. It's then explained that their spiritual companions have come to help humans relearn love and harmony. The spirits (each represented by Disney characters) are introduced one by one, and they use their magic to initiate a musical celebration and reinstill the heartbeat of love in the audience.
- Each spirit's costume is designed with a specific gemstone motif. The Spirit of Laughter's is amethyst, Friendship's is citrine, Truth's is emerald, Adventure's is sapphire, Love's is ruby, and Imagination's is diamond.
- In supplementary material, the spirits are designated to be a sea serpent, a ram, a frog, a turtle, a griffon, and a deity (in order of introduction).
- The elemental spirits appear as Audio-Animatronics on Mickey's show float.
- The 5th Anniversary theme, "Sea of Dreams," closed out the show during its initial release. After anniversary celebrations ended, this was removed. During the 10th Anniversary celebration, "It'll Be Magical" was used in a similar manner.
- The show's soundtrack has been released on two separate occasions: once after its initial release in 2006, and again for the park's 10th anniversary in 2011.
- A performance on March 11, 2011 was interrupted by the Tohoku Earthquake, which measured 9.0 on the Richter Scale. The show went on for at least a minute before the show's soundtrack was stopped. This was followed by the normal "this performance cannot continue" message, which was delivered in Japanese, and then in English. The English version, though, was cut off by J-Alert tones and an earthquake message delivered in Japanese and English. Video of this can be found on YouTube, along with the aftermath. There was no damage to the animatronics, and the only damage seen in the aforementioned video was a set of speakers knocked off a lightpole and held up only by a tether (which, fortunately, did not snap).
