The Shrew that Flew

Badger's having a birthday party and Harry and Lil are getting ready, but just as Lil is getting her favorite 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!
