This collectable hardcover edition will feature a beautiful cover and deluxe packaging, including color interior text and illustrations! From the bestselling author of Charlie and the Chocolate Factory and Matilda. Mr. and Mrs. Twit are the smelliest, nastiest, ugliest people in the world. They hate everything-except playing mean jokes on each other, catching unsuspecting birds to put in their bird pies, and making their caged monkeys, the Muggle-Wumps, stand on their heads all day. But the Muggle-Wumps have had enough. With the help of Roly-Poly Bird, they set out to get some well-deserved revenge.
