Patterson Pepps best friend is Raf, a giraffe. Raf and Patterson were born on the same day and grow up together as Patterson lives next to the zoo. When they are old enough to start school, they are very excited. On the first day, Patterson even stuff all kinds of plants into his backpack to make sure that Raf will have enough to eat. When Patterson realizes Raf wont be to join him at school he is very sad. Gradually Patterson is enjoying school more than he expected and actually makes a new friend: Yous. Raf, however, feels left out. Fortunately, Patterson comes up with a brilliant plan to bring Raf to school and to unite his two best friends.
