At the zoo, the great yawning begins at precisely eight o'clock. The tiger yawns, and then the swans join in. One animal infects the next. Finally, it's eight-thirty. Everything that crawls and flies is now yawning busily. The llama yawns, the kangaroo, the bear, the zebra, and the wildebeest. The sloth thinks to himself, "That's fine, thankfully there's finally some peace and quiet!" Yawning is contagious, is laughter too? And after the great yawning comes contented sleep. A beautifully and amusingly illustrated bedtime story.
