"The Three Little Pigs" is a popular children's story about three pigs who each build their own houses. The first pig builds a house of straw, the second pig builds a house of sticks, and the third pig builds a house of bricks. Each pig hopes to protect themselves from a big bad wolf. The wolf comes along and blows down the straw and stick houses easily, forcing the first two pigs to seek refuge with their brother in the brick house. Eventually, the wolf tries to blow down the brick house but fails, and the pigs are safe inside.
