Have you ever met someone so grumpy, mean, and downright nasty that they make your teeth ache? Meet Mr. and Mrs. Twit, the smelliest and ugliest couple you could ever possibly imagine! They spend their days playing horrible, nasty tricks on each other, like dropping a glass eye into a drink or hiding squiggly worms in a plate of spaghetti. But the Twits are not just awful to each other. They also trap innocent birds to bake into their terrible Bird Pie, and they force their poor pet monkeys, the Muggle-Wumps, to stand on their heads all day long! Finally, the Muggle-Wumps have had enough of this dreadful treatment. They do not just want to escape their cages; they want to get even! Can these clever monkeys outwit the ghastly Twits and teach them a lesson they will never forget? Get ready for a hilarious, laugh-out-loud adventure where the worst people in the world might just get exactly what they deserve!
