Like a great friendship, Mo Willems's Elephant & Piggie series gets better with time. Featuring two lovable and funny characters: an optimistic (and sometimes reckless) pig and a cautious, pessimistic elephant, these books make reading irresistible to beginning readers. Each book has been vetted by an early-learning specialist (and many adorable early learners ). In Watch Me Throw the Ball , Gerald is determined to teach Piggie that ball-throwing is serious business . . . but Piggie is just as serious about having fun.
