以下是英语版的故事情节：

Once upon a time, there were three little pigs. They decided to build their own houses. The first little pig built a house out of straw. The second little pig built a house out of sticks. And the third little pig built a house out of bricks.

One day, a big bad wolf came to their village. He was hungry and wanted to eat the three little pigs. So he went to the first little pig's house. 'Little pig, little pig, let me come in!' said the wolf. 'No, no, not by the hair on my chinny chin chin!' said the first little pig. But the wolf huffed and puffed and blew down the straw house.

The first little pig ran to the second little pig's house. The wolf followed him. 'Little pigs, little pigs, let me come in!' said the wolf. 'No, no, not by the hair on our chinny chin chins!' said the two little pigs. But the wolf huffed and puffed and blew down the stick house.

The three little pigs then ran to the third little pig's house. The wolf followed them again. 'Little pigs, little pigs, let me come in!' said the wolf. 'No, no, not by the hair on our chinny chin chins!' said the three little pigs. But the wolf huffed and puffed and couldn't blow down the brick house.

The big bad wolf was very angry and tried to climb down the chimney to get into the brick house. But the clever little pig had a pot of boiling water on the fire. The wolf fell into the pot and ran away, never to be seen again.

From that day on, the three little pigs lived happily ever after in their strong and safe brick house.
