One Saturday, in the middle of June, one bright and windy afternoon, all the creatures by Piggyback Wood were getting ready - as fast as they could. There was only a short time left to prepare for the birthday party at Badger's lair. On the invitation was written in red: Will guests please arrive with a hat on their head? Harry and Lil are getting ready for Badger's party, but just as Lil goes to get her hat off the washing line, it flies away. Oh no! If only shrews could fly... "If birds fly, why can't shrews fly, too?" Adventure abounds in this delightful third Harry and Lil book from the author who brought you Hog in the Fog and The Hog, the Shrew and the Hullabaloo.
