There are three little pigs in the forest. Their mother wants to go shopping. She tells them to play in the mud pool(泥塘). The pigs jump into the mud pool. Suddenly, a big wolf sees them. He starts feeling hungry. The big wolf tells them he will take them to a beautiful place(地方). The youngest pig is very clever(聪明). He tells the wolf they will take a bath (洗澡)first. The wolf thinks it is better to eat clean(干净)pigs. Then he has a rest under a tree and falls asleep(睡着). The pigs tie the wolf with a rope(绳子). When their mother comes back, they tell their mother the story. Their mother is very happy.
