Exploring outer space and the ocean is exciting, but what if you left something very important at home? 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!)i and Colette is obsessed with the sea (Waves! Fish!). Staying home is not an option, so they each get busy. Garcia builds a rocket ship that's snazzy and silver. Colette's shiny submarine is perfect for deep-sea dives. And they wish each other well on their travels. It turns out the Milky Way really is amazing and the ocean floor is truly spectacular, but Garcia and Colette both realize they left something very important back home. Exploring your favorite place can be terrific, but maybe the company is more important than the destination.
