Arthur the Troll was Challenge One of the Three Impossible Challenges on Goblin Mountain. He only bought cheap shampoo, so he had greasy hair, and he carried a knobbly wooden club with a nail through it. He was as tall as three men. He gives you a letter that says,
To Whom I Am About To Eat:
You have stepped on to my patch of the mountain like the fools you are. And now you must face my challenge, you idiots. And it is a mighty challenge indeed! No one has ever succeeded in beating me at this challenge, not in hundreds of years. And the challenge is this: You cannot get past me unless you guess my name. And you will NEVER guess my name. And when you have FAILED to guess my name, I will CRUSH YOUR BONES UP and EAT you. And THAT is my challenge.
Yours Sincerely,
Arthur the Troll
