For instance one of the most important details in the Fable, “The Princess and the Pea” is the pea. How about if instead of a pea there was a pumpkin or even a watermelon under all those mattresses? What would the princess do? Would it change the story. Or, how about if instead of the mattresses, the princess had to sleep on a stack of hay bales. I’m sure that would change the story.
Have a go at it. Let me know what you come up with.
