The Three Little Pigs' The Three Little Pigs is a popular nursery rhyme that tells the story of three pigs who build three houses of different materials. The first two pigs build their houses out of straw and sticks, respectively, while the third pig builds his house out of bricks. In the end, the third pig's house is the only one that survives the Big Bad Wolf's huffing and puffing. The third pig is often referred to as 'PIGGY' in the nursery rhyme, which can be abbreviated to 'TOE' in a crossword puzzle.
