A tiny sea snail with a big dream longs to explore the wide world. She writes a message on a rock asking for a lift—and to her surprise, a great big, kind humpback whale responds!
 
Together, they embark on a breathtaking journey across the globe. They pass fiery volcanoes, icy glaciers, exotic islands, and deep, dark oceans. The snail marvels at the beauty and scale of the world, riding happily on the whale’s tail.
But when the whale becomes stranded in a bay, unable to return to the sea, the snail bravely takes action. Despite her size, she crawls to a nearby school and alerts the children and teachers, who help save the whale.
 
In the end, the whale is freed, and the snail returns home a hero. Inspired by her journey, she invites the other snails to travel too—on the whale’s back.
