There was a wolf called Wilson Who never brushed his hair. He never washed his paws or face Or changed his underwear. Will anyone be able to persuade Whiffy Wilson to change his grotty ways for something far less stinky? Peew! Let's hope so. A fantastically funny verse from the brilliant Caryl Hart, with grubby-but-great illustrations from the hugely talented illustrator of The Dirty Great Dinosaur.
