 
From the bestselling author of Charlie and the Chocolate Factory and The BFG!
Mr. and Mrs. Twit are the  smelliest, nastiest, ugliest people in the world. They hate  everything—except playing mean jokes on each other, catching innocent  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. They don't just want out, they want revenge.
