Fierce Milly is back with a crash. Her mum says she can't have a dog until she's sensible, but Fierce Milly doesn't give up that easily. From a less than safe distance, Susan and Billy watch Fierce Milly conjure up a very big invisible dog with huge teeth, called Crazy Eyes. And anyone who laughs at Crazy Eyes will grow a tail. Fierce Milly knows just what to do to get Crazy Eyes back when Cecil Nutt steals him. He'll never forget her vanishing trick. She even knows a magic spell to make Crazy Eyes visible. At last, a real dog appears which smells as real as it looks. Using plenty of aromatherapy bubble bath, Fierce Milly, Susan and Billy give it a once-in-a-lifetime bathtub experience before it returns to its owner.
