Dad's bum has blown off! With a hiss and a roar, it's gone out our front door ... After a meal of cabbage and peas, Dad's bum not only lets off a smell, but blows off entirely and sets off on its own around the town! 'Let's chase it, Dad, before it's too late,' says the red-panted hero in this latest New Bum escapade. Forget about a car chase, this is a bum chase - past joggers in tights and bikers with lights, until the Police have to intervene. Hilarious rhymes and drawings capture the spirit of this brilliant addition to the international hit series, cracking up readers from Aberdeen to Invercargill.
