Orville lives at the zoo, surrounded by animal pals who go on exciting adventures. A hang gliding rhino! A deep-sea diving giraffe! Orville struggles to keep up, until one day he concocts an adventure all his own: build a spaceship and fly to the moon all by himself. Can one tiny penguin get there alone? Or will Orville find that sometimes you need a little help from your friends? Marcie Colleen's playful text and Emma Yarlett's charming, whimsical illustrations are sure to delight both children and their parents.
