A funny, vibrant underwater adventure about colours, rumours and how the smallest creature of all can cause the biggest reaction - and maybe even save the day! This glorious marine mystery, from the creator of the award­winning One Fox: A Counting Book Mystery, features a host of sea creatures from an orange crab to a green turtle, a yellow eel and even a purple puffer fish. But it all begins with one tiny pink fish who sets off a chain reaction of chaos beneath the waves until suddenly ­ SNAP! ­ she finds herself all alone in the ocean. Where has everyone gone, and how can such a tiny creature rescue her friends? Kate Read's stunning illustrations are as rich and bright as an aquarium of tropical fish and readers will love following the trail of colourful creatures through to the surprise finale. Boo also includes a page at the end showing readers how to mix their own colours.
