THE TIMID MOUSE.
Reading edition
A mouse was kept in such distress by its fear of a cat, that a magician, taking pity on it, turned it into a cat. Immediately it began to suffer from fear of a dog; so the magician turned it into a dog. Then it began to suffer from fear of a tiger, and the magician, in disgust, said, 'Be a mouse again. As you have only the heart of a mouse, it is impossible to help you by giving you the body of a noble animal.'
It is hopeless to try to accomplish anything without pluck.
