Fra forlagets omtale: Mr Twit is a foul and smelly man. Mrs Twit is a horrible old hag with a glass eye. Together they make the nastiest couple you could ever hope not to meet. Down in their garden, the Twits keep Muggle-Wump the monkey and his family locked in a cage. But not for much longer, because the monkeys are planning to trick the Twits, once and for all...
How do you outwit a Twit? Mr. and Mrs. Twit are the smelliest, 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.
