A children's story about three pigs, each of whom builds a house to be safe from the Big Bad Wolf. The first pig makes a house of straw, and the second a house of sticks. Both finish quickly and spend their time amusing themselves, while the third pig is building a house of bricks. When the wolf arrives at the door of each house, he boasts, “I'll huff, and I'll puff, and I'll blow your house down.” He succeeds with the houses of straw and sticks, so the first two pigs take refuge in the brick house, which the wolf cannot blow in. In some versions of the story, the wolf eats the first two pigs.
