What was the beginning plot of The Three Little Pigs?

Three pigs each build their separate houses, each using a different material (one straw, one sticks, one brick). The Big Bad Wolf, anxious to eat them, asks the first pig to come out of his house of straw. When the pig refuses, the wolf uses his powerful breath to blow down the straw house. The process is repeated at the stick house of the second pig. Again, the wolf blows it down. At the third house, the wolf tries to blow it down, but fails. When he next tries to sneak into the brick house through its chimney, he lands in a boiling cookpot.

In some versions, the first two pigs are eaten when their houses collapse. In others, they escape to the sturdy house of the third pig. In earlier versions, the wolf was eaten by the third pig. In later versions, he was merely scalded and traumatized, and never threatened the pigs again.
