All the Elephant and Piggie books are hysterical. They are full of humor and important lessons that any preschooler will relate to. We love them all but my son and I's favorite is Let's Go for a Drive. Elephant and Piggie plan to take a drive and assemble all the things necessary for their trip only to discover that they don't have a car! While Elephant is sobbing over their ruined plans Piggie suggests they play pirates instead. They proceed to have a fabulous adventure instead of going for a drive. My son William and I giggle and laugh while we read this book but the underlying lesson really made an impression when our plans with a friend were cancelled at the last minute. William was about to burst into tears when we talked about this book and made plans for our own new adventure. Elephant and Piggie saved the day! I just might send Mo Willems a thank you.
