Glitched Town

From Glitches

From the game The Legend of Zelda 2: The Adventure of Link for the NES.

Do the Glitched Palace glitch on the roof of the tallest building in Darunia. You'll fall and land in a strange town with a blue sky (instead of Darunia's red sky) where people give different clues. It is possible this could have been an unfinished town left in by the programmers. When you leave the town, you'll be stuck in the middle of the ocean. If you have not found the lost child in the cave, the game may act as if you have.
