There are several things that must be done before entering the Lizard Labyrinth. First, go to the graveyard via the Lost Forest. That can be accomplished via going North, West, South, and West in the Lost Forest. Now go north past the Lynels until you have gotten in the graveyard. Now go right one scene, and up two to the upper right part of the graveyard. Now, move the third tombstone in a set of 4 in the second row. When that happens, a passageway opens.
Inside is the Magical Sword. In order to receive the Magical Sword, Link must possess 12 container hearts (including 4 Triforce fragments), the White Sword, and the Magic Shield. When Link equips the Magical Sword, his attacking powers is two times greater than when he had the White Sword.
Now go down one scene and go east to leave the graveyard. Keep going east and take the second passageway. Touch all the Armos if possible, but if you touch the Armos in the upper right part of the top row of Armos, you'll come across the Power Bracelet. Grab it -- you can now move Rocks and other stuff that Link couldn't previously move in the overworld.
Continue going east until you are in the Lost Hills. Go up four times,
and when there, be careful for a leever lurking up from under. Be sure
you got the Red Medicine Bottle and 100 rupies.
