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. Badger's having a birthday party and Harry and Lil are getting ready, but just as Lil is getting her favourite hat off the washing line to wear, it blows away. Harry says it's gone for good, but Lil says you should never say never if birds can fly, shrews can, too. An umbrella doesn't work, nor does a fan... and then Deer comes along with a big green balloon!
