Professor Puffendorf is the world's greatest scientist. Her laboratory is a wonderful place full of odd-shaped bottles and tubes, strange machines that hiss and squeak, and an old cabinet marked 'Top Secret'. And in that cabinet lie her secret potions that have never been tested, potions that can make your wildest dreams come true. One day she goes out and leaves her assistant, Enzo, behind with her pet guinea-pig, Chip. Now is Enzo's chance to get his hands on the potions, but first he has to try them out on Chip. Will they work? What will happen to Chip? And what will happen to Enzo? This successful picture book is now in paperback.
