"Oh, children," said the Lion, "I feel my strength coming back to me. Oh, children, catch me if you can!" He stood for a second, his eyes very bright, his limbs quivering, lashing himself with his tail. Then he made a leap high over their heads and landed on the other side of the Table. Laughing, though she didn't know why, Lucy scrambled over it to reach him. Aslan leaped again. A mad chase began. Round and round the hilltop he led them, now hopelessly out of their reach, no letting them almost catch his tail, now diving between them, now tossing them in the air with his huge and beautifully velveted paws and catching them again, and now stopping unexpectedly so that all three of them rolled over together in a happy laughing heap of fur and arms and legs. It was such a romp as no one has ever had except in Narnia; and whether it was more like playing with a thunderstorm or playing with a kitten Lucy could never make up her mind."
