How do animals live? What do they eat? Is a human being an animal? Children have all sorts of questions about animals, and in My Animal Book those questions are answered. A little girl named Koko helps children think about animals and make comparisons with their own lives. There are also three intrepid explorers who go on adventures to a variety of places to find out about different species. Young readers investigate each topic by playing and learning.

The book is energetic and bold in its illustration, with contributions from a variety of illustrators. It has a sense of humor, and its large format makes it feel friendly and approachable for children ages five and up.
