Bertie the gardener is happy with his life, so is Oscar - his dog. However, this happiness turns to discontent when Bertie sees George looking 'important' in his new bowler hat. Bertie wants one just like it, so that he can look important too. Consequently, he hangs up his comfy old hat and that's when his adventure begins.

There's a fun activity page at the back of this book so that children can learn more about different types of hats and their names.
