|summary=Most children want a pet at some point. Mossy Monster wants a pet itch more than anything else in the world. But his family (refreshingly consisting of a Granny, an Uncle and a sister) have all sorts of reasons why he shouldn't have one and his sister just seems to delight in tormenting him - as sisters do. But Sister comes though in the end with a crafty plan that will help Mossy get the Itch of his dreams, and make sure the grown ups do all the work as well. There is never a dull moment in this book with temper tantrums, rude rhymes and absolutely delightful illustrations. The best part of all though is the way the adults are so easily bamboozled.
