Say What? asks the question what are animals really saying when they make the noises that they do. “When a cow says Moo, does she really mean who?” DiTerlizzi, suggests an answer for many different animals including lions, snakes, owls, ducks, and more. Each meaning rhymes with the original noise of the animal. This book is great for toddlers because there is repetition, rhythm, and rhyme, which are all great tools for teaching the intricacy of language. The illustrations are bright and silly. Each animal has a fun expression on their face that shows the playfulness of the book.
