Each page has a cute rhyming poem and pictures of different animals. In every set of animals, one is not like the other. Each poem asks the reader to find the odd one out! I love the simple, yet wonderfully colorful illustrations in this book. I like that some pages put forth a relatively easy challenge, however, some were even tough for me! It encourages children to really see what is going on in the page, and to really pay attention to the finer details in each picture! I also like that each poem describes unique characteristics to each animal. It really seems to be educational on so many levels.
