I really liked the twist of William being Rumpelstiltskin, because when you think about the original story, he really WAS a fixer of a sort.

“I help people, but I don’t like them,”
Fair enough. I expect most of the people he helps were put into trouble by some other human, or did it to themselves. He must encounter a lot of ninnies...

Hahahaha! That IS what he looks like. Hobgoblins aren't as popular in literature or elsewhere as they used to be.

A nice happy ending for everyone, especially the children!
