Mother Pig sends her three little piglets out into the world to live on their own.
The first little pig builds a house of straw, but a wolf blows it down and eats the pig. The encounter between wolf and pig features ringing proverbial phrases:
One day the big bad wolf came and knocked on the first little pig's door and said, "Little pig, little pig, let me come in." And the little pig answered, "No, no, I won't let you come in, not by the hair on my chinny chin chin." "Well," said the wolf, "then I'll huff and I'll puff and I'll blow your house in." So he huffed and he puffed and he blew the house down and ate the little pig.
The second pig builds a house of sticks, has the same conversation with the wolf, and meets the same fate.
The third pig builds a house of brick. The wolf cannot huff and puff hard enough to blow the house down. He attempts to trick the third little pig out of his house, but the pig outsmarts him at every turn. Finally, the wolf threatens to come down the chimney, whereupon the third little pig boils a pot of water into which the wolf plunges. The little pig cooks the wolf and eats him.
