The 'This Little Piggy' story typically goes like this. There are five little piggies. This little piggy went to market, this little piggy stayed at home, this little piggy had roast beef, this little piggy had none, and this little piggy cried 'wee wee wee' all the way home. It's a simple and charming nursery rhyme often used to play with a baby's toes, one toe for each piggy in the story.

One type of fanfiction could be a humorous crossover where the characters of the Justice League encounter the 'This Little Piggy' scenario in a comical way.
