Following on from the hugely successful I Wonder Why series, I Wonder Why (Flip the Flaps) is a fun way for young children to discover the answers to questions about their favourite subjects, while also flipping the flaps and spotting the scene changes.Whales and dolphins swim through the flaps of this book - watch dolphins jaw-clapping, a blue whale's blow hole spouting and spinner dolphins leaping. The questions uncover essential and extraordinary facts about feeding, communication and much more, and provide a great first knowledge of these fascinating sea mammals.
