I seem to have hit a roadblock. I can ride the unicorn to what I'm assuming is the royal gardens, but I apparently don't have what the guard wants. It seems he wants a weapon from what I've read on these boards, but what exactly is he looking for?

I've given that stupid soothsayer three gold coins; is the fourth one in that garden where I can't get to it?

In the enchanted forest, I've killed the goblin, the vampire, and the wood sprite, had a drink with the dwarf, been mocked by the pixies, been ignored by the sphinx, fed the stupid rabbit, and given my ticket to the elf numerous times. What am I missing?

Also, I'd found the boat, and I even had the gold key to turn it on. However, I didn't realize the significance of my find at the time and didn't bother making a note of where I found it. I don't remember what I did with it (it was late at night when I played) but what I DIDN'T do with it was fish. Now, I'm fishless and boatless. Where can I find these, especially since I've already untied the boat and I don't think I retied it anywhere?

My inventory:
Sack
Carrot
Rope
Branch
Silver Key
Gold Key
Sword (for the second time)
Shovel
Hammer
Nails
Bow
Arrow
Fishing pole (but no idea where the boat went)
Club (beaten down the wall)
Ticket (used it)
Sunstone (petrified the troll)
Leaves (but no supposed sorcerer; where's he?)

Random yes-or-no questions: is there any significance in the game to...
The tractor in the toolshed?
The dog on the volcano?
The log in the road?
The dwarf drinking ale in the enchanted forest?
Those darn giggly pixies?

Any help (in hints OR spoilers; I like both) would be VERY appriciated!
