Best friends Garcia and Colette are eager to go exploring - only they can't agree on where to go. Garcia loves everything about space (stars! planets! meteors!) and Colette is obsessed with the sea (sand! coral! fish!). So Garcia builds a rocket ship that's snazzy and silver, Colette constructs a submarine that's perfect for deep-sea dives, and they wish each other well on their travels. But even though they find some amazing things on their journeys, the friends quickly realize they each left something very important back home.
