The Legend of Zelda/Underworld

Hyrule's underworld is made up of 9 labyrinth dungeon's. The entrance to some dungeon's, particularly the earlier ones, are right out in the open, while some require a step or two to expose. Each labyrinth is in a particular shape, be it an object, symbol, or even a letter of the alphabet. Unlike the overworld, the underworld of the 2nd quest differs drastically from the 1st quest.
