First of all you have to be a kid so go back to the temple of time and return to a kid then go to kakariko and enter the well. You might have to play the song of storms to the windmill guy but i forgot.When you get inside go to the hall on the left and walk against the inner wall and you should go through the wall and find a key.Now go to the right hall, this time go around the corner and walk against the inside corner and you will find another key.To get the third key go back to the left hallway and take the first visible hallway to your left.When you get to the room with coffins in it only open the one in the top right corner.To open a coffin just light the tourch that is near it. Now make your way to the back of the well and play Zelda's Lulluby at the Triforce symbol. Then right in back of you there should be an invisible wall, go though the wall and don't go near the center becuse there is an invisible floor. Go to the top right corner to get a compass, stay close to the wall because there is another invisible floor. Now if you walk into the wall you will walk through it and be back n the hall.go to the right and then to the left. You should fall through the floor, when you land you will be in a room. Blow up all the rocks you find. Behind one of them there should be a map. Now find all the silver rupees and exit. When you get all te way up the ladder you will be in a room. Go through the door and go through the wall (invisible door). Now go straight. Fall in the hole and go through the crawl space. Go through the hall into the big room. there should be hands trying to grab you. Let one grab you (no i am not trying to kill you) and his head should pop up. slash at the head. Continue 'til he is destroyed and you have won the Lens of Truth. Now go to the Temple of Time and return to an adult, then on to the Shadow Temple!!!
