The Elephant and Piggie books, invented by Mo Willems, are favourites of my 9-year-old daughter, who is otherwise long past beginner readers. She has asked for more Elephant and Piggies for her tenth birthday. She feels a lot of similar level stories are ‘too babyish’ for her but an enduring interest in the Elephant and Piggie series demonstrates the extraordinarily wide age appeal of these stories. As adult co-reader, I enjoy them as much as she does. These books are more than ‘dual audience’. Dual tends to refer to ‘one developmental phase of childhood plus the adults who read alongside’, but in this case the appeal is young childhood, middle childhood, right through.
I listened to an interview at The Yarn, with Travis Jonker and Colby Sharp, in which Willems says: There is no formula when it comes to writing picture books.
There is no ‘formula’, because ‘formula’ suggests ‘low quality’ a la R.L. Stein’s Goosebumps series. But there is a certain structure that all good stories share. The Elephant and Piggie stories do conform to this structure. This structure provides a coat hanger for the originality that Willems and his writing team bring to each story in the series. Willems describes this structure as ‘a trellis’. He describes himself as a structuralist, ‘but more of a formalist than other people’ in the way he writes and constructs his stories. He says this comes from his time working in television. Television writers have to understand structure in order to get ideas out on time, and when your task is to create something exactly eleven minutes long it becomes even more important.
