Wilbur the Wave is just an ordinary wave who changes whenever Mr. Moon decides to change him. Along with his best friend, Walter Whale, Wilbur happily travels the world and the seven seas, where he watches all the people on the beach and plays with the sand crabs. But one day, when Wilbur lands on a beautiful beach, his biggest adventure ever begins.
As Wilbur swirls about with his pal, Sandy Crab, a pretty little girl scoops them both up in her bright red pail. Wilbur thinks Susie is very cute, but nervously wonders what will happen to him. After Susie carries Sandy and Wilbur home in her beach bucket and dumps them into a baby pool in her backyard, Wilbur decides he must do something right away to save them. But he cannot do it without help from Mr. Moon and Susie.
In this warm, whimsical tale, only time will tell if a wave and a crab can find their way back to the ocean, where they can once again share their beauty with the world.
