You dumb thing!"" The very first time Jack throws his new wing-a-ding, it gets stuck in the Willoughbys' tree. His friends gather to help get it down, but everything they throw at it (boomerang, fishing line, broom, etc.) also lodges in the leafy branches until Jack changes his tune: ""Wing-a-ding, you're a good thing,"" he whispers, and away it zooms. The cheery rhymed text is well matched by Gammell's usual exuberant illustrations; gnomelike figures dance between billowing grass and leaves, and around a parti-colored tree trunk that changes size with each new view. Theatrical and fun.
