ALSO KNOWN AS "THE DAY MY BUTT WENT PSYCHO" 'This is my story. It really happened. It’s all true. Not even the names have been changed. Like most people I took my bum for granted. I agreed to tell my story in the hope that others could learn from it. If this book can save even just one person from making the same mistake, then I will be happy. Who knows? The next bum it saves might be yours.' Zack Freeman is ready to tell his story. The story of a boy, his runaway bum and some of the most dangerous bums in the world including kamikaze bums; nuclear bums; and Stenchgantor, the Great Unwiped Bum. With the help of The B-team (a crack bum-fighting unit comprising three of the best bum-fighters in the business: the Kicker, the Smacker and the Kisser), Zack will risk methane madness crossing the Great Windy Desert, death by stink-bog in the Brown Forest, and the perils of the Sea of Bums before finally descending into the heart of an explosive bumcano to confront the most psycho bum of them all - His own!
