Elves play pipes while the goblins sing

For those creative lot among you....
Players in my 7th Sea game are being sent on a quest to allow them to enter the Summer Country, home of the fairies and piskies.
I'm looking for an appropriate quest, and turn to those of you who are not in my game and perhaps have a mean streak in you to offer me suggestions.
My two main qualifications:
It should sound like something you would encounter in a fairy tale of some stripe.
If it would benefit a pragmatic, somewhat otherworldly Scottish family who is setting the quest, that would be especially good.
My players are warned--clicking on comments may reveal spoilers.

Robin Goodfellow will take his queen, once upon a midsummer night's dream.

Your fault.

And a gold star to the Selkie from the northron wastes. (:
I bet you'd come up with a really good quest.
