Meet Andy and Terry. They make books together in the world's coolest treehouse! They've got loads of different storeys in their home in the sky: you can find a marshmallow machine, the world's most powerful whirlpool, a penguin ice-skating rink, a tank full of sharks and a human pinball machine, among many other things. But none of these help them agree on their special story for World Book Day - and it's not just Mr Big Nose keeping an eye on them now, but the story police too! Terry's Dumb Dot Story is a special World Book Day Treehouse adventure from Andy Griffiths and Terry Denton, told through a combination of laugh-out-loud text and fantastic cartoon-style illustrations. Well, what are you waiting for? Come on up!
