The story of the Three Little Pigs is a popular folk tale about three siblings who each build their own house. The first pig constructs a house of straw, the second pig builds a house of sticks, and the third pig makes a sturdy house of bricks. A wolf comes along and tries to blow down their houses. He easily destroys the straw and stick houses, but he cannot blow down the brick house. The tale emphasizes themes of hard work and the importance of building a strong foundation for safety and security.
