Harold brings his purple crayon with him everywhere. He can use it to solve problems. One day he drew a couple of things like a castle. He drew a lot of flowers (More than he could even count.) But the last one ended up being a fairy and Harold didn't have anything to wish for but he wanted to take a wish with him. He wished he would get a wish later and he did. Later he got a flying carpet. He didn't know how to land the carpet after he started flying.   But finally he did it with his purple crayon.
