Don't know if anyone still checks this forum but I just started playing this game. I cannot for the life of me find the final regular key in the Stone and Chill level? It appears I need it to get what I think is the boomerang. If anyone can give me a hint that would be great. I have the boss key and the other level item but I have looked everywhere for another regular key with no luck. I think I have bombed all the arrow spots.
I think the key you're looking for is hidden behind a rock if I recall. I haven't played this quest in awhile. It's in a room near the top left corner of the screen.
Titanium Joopy did a Let's Play of this quest.
