Puss in Boots
The ogre received him as civilly as an ogre could do, and invited him to sit down. "I have heard," said the cat, "that you are able to change yourself into any kind of creature that you have a mind to. You can, for example, transform yourself into a lion, an elephant, or the like."
"That is true," answered the ogre very briskly; "and to convince you, I shall now become a lion."
The cat was so terrified at the sight of a lion so near him that he leaped onto the roof, which caused him even more difficulty, because his boots were of no use at all to him in walking on the tiles. However, the ogre resumed his natural form, and the cat came down, saying that he had been very frightened indeed.
"I have further been told," said the cat, "that you can also transform yourself into the smallest of animals, for example, a rat or a mouse. But I can scarcely believe that. I must admit to you that I think that that would be quite impossible."
"Impossible!" cried the ogre. "You shall see!"
He immediately changed himself into a mouse and began to run about the floor. As soon as the cat saw this, he fell upon him and ate him up.
