There's three magical balls of star light who want to travel to Earth. Along the way, the meet up with Imagination, who lives on the moon. She gives them physical forms and names: there's a guy (Solar) and two puppets (Luster and Moonshine). The travel around in a "space bubble" superimposed in front of stock footage while they discuss and joke about the educational material they're watching. They sometimes cut away from the footage for short segments where they talk with Imagination.
