Oh no, a dragon! We better run and tell the king!
The dragon burnt the door down and ate some sheep. Afterwards it headed back to the pool.
The town figured they would offer two sheep to the dragon every day.
But one day, they ran out of sheep. They started doing a lottery every day, where one person would be drawn to be fed to the dragon. One day, the king's daughter was chosen in the lottery. The king didn't want to, but ended up agreeing that a lottery is a lottery.
But suddenly, a brave knight came to kill the dragon.
I'll save you!
The dragon was slain, and the king's daughter returned to the castle. And they lived happily ever after, i think.
