A to Z book by Sandra Boynton 

A shy hippo makes a big impact in this anniversary edition of a Sandra Boynton classic. A hog and a frog cavort in the bog. But not the hippopotamus. A cat and two rats are trying on hats. But not the hippopotamus. The original But Not the Hippopotamus was an instant favorite among children and parents. Now this hilarious Boynton book is back in a Special 30th Anniversary Edition, complete with its silly rhymes and humorous, charming illustrations. In this simple, playful board book, a shy hippo watches as other animals engage in social activities. Finally, the other animals invite the hippo along and, after dithering a moment, she leaps into the fun...with hilarious results. The repetitive, enjoyable rhythm, cheerful mood, and well-crafted, simple rhymes will endear this story to toddlers everywhere. This anniversary edition has an enlarged trim size and metallic ink on the cover, making this Boynton classic even more special. Published By Simon & Schuster on 1984-10-11
