This is the original that all the costumes and characters are based on when Dr. Suess is mentioned. I admit, the first time I read this book, like many by Dr. Suess books, I was tongue tied! That is part of the fun. The more my kids requested it however, I started really being able to fly thru it- and they requested it alot. This book is so much fun to read and animate to my children. It also brings about the idea of 'sight words' because the rhyming and repetition. Some of the Dr.'s books are just rhyme, but I enjoy those that do follow a story and make some sense. Awesome fun book that will entertain your children and your tongue for many many years!
