This is the 2nd '5th quest' I'm working on. Rather easy for me: the only things I'm missing right now are the whereabouts of the Magic Sword (stolen?) and one of the Heart Containers.
Curiously enough, I never found the wooden boomerang. Got the magic one in Dungeon 3.
Working through Dungeon 5 now, and I think I know where Dungeon 6 is. Already found 9. Need to find 7 and 8.
UPDATE: Found the Magic Sword and 5th HC. When I found what I thought would be Dungeon 6, I actually found Dungeon 7. 7 led me to 8, and 8 would have led me to 9 had I not already found it. But the location of Dungeon 6 has me completely stymied.
2ND UPDATE: I cannot believe that I would make the same mistake TWICE!!!
The first '5th quest' I completed, I discovered Dungeon 8 before I should have, then completely forgot that I had found it when I needed to go back, aimlessly looking for a new opening.
Well, I did it again! I found Dungeon 6 a while ago, and completely forgot about it! (Ironically enough, the clue to find 6 DOES work for 7!)
Yeesh!
