Save Uncle Crimbo!

Upon getting the quest, it seems the next time you use your Cottege/House, you'll be visited by a Ghost. Not THE Ghost, but he'll tell you that you're going to be visited by three ghosts. Ghost of Crimbo from the way-way-past, a Ghost of Crimbo Right-about-now, and a Ghost of Crimbo of the Not-Too-Distant-Future.

The next time you use your Cottege/House - the Ghost tells you about Crimbo Rock, and that you'll have to search for three items to get Uncle Crimbo to remember.

Re-visiting the Mountains will now have Crimbo Rock.

You'll need to adventure in the 'Simple Tool-Making Cave' until an elf drops a leaf, and some string. When you visit Ugh, one of the options will be a 'Rolled Leaf' - grab that, and make some 'Fire' while you're at it.

Combining the two give you a 'Lit Cigar' - and when used, shows that you're on the 'Right Track' in finding Uncle Crimbo.
