[2][3] When it later aired on Playhouse Disney, the movie was split in half as two episodes at the end of Little Einsteins' first season, with many scenes of the original cut being edited out or shortened to fit the show's runtime.

The movie features Beethoven's Ninth Symphony, and includes artwork such as Wheat Field with Cypresses by Vincent van Gogh, The Great Wave off Kanagawa by Katsushika Hokusai, Woman in the Garden by Claude Monet, and Navajo woven art (the last of which also makes a cameo in the series' intro).

Along the way they must traverse a Musical Roller Coaster, collect yellow leaves to feed the caterpillar along the road, and venture through a dangerous ocean.

After reaching the musical tree of many colors, the caterpillar manages to merge into a grown Monarch Butterfly, much to everyone's delight.

The group untangles them and the apex spider gives chase, along with another horde of bloodthirsty bats, but everyone escapes the cavern unharmed.
