Go through the left-hand door. Let the bee kill the tentacles while you look under the top-left pot for aSmall Key. The bottom-right pot hides a door-release button. The other two hold arrows so you might as well grab them while you're here. Go back down through the door you came in by.
Now go through the right-hand door. Once the tentacle monsters are destroyed, unlock the door and go through.
Here at last is yourL-1 Sword! If you want to keep the Gold Bee, switch to the Bug-Catching Net and bottle it, otherwise you'll lose it forever after opening the sword chest. Now hit the sphere to lower the blocks and go through the door to the right.
Open the chest for 10 Bombs (bomb the wall above you if you want 60 rupees). Lift the top-left pot for aSmall Key. Go to the right and open the chest for the Map. The pots contain Bombs so fill up. If you want 40 rupees, bomb the top wall. Otherwise go west, west, and bomb the wall to continue.
Open the chest for theSmall Shield then go through the locked door (if the blocks are raised go back east and hit the sphere to lower them). Open the chest for the Compass (bomb the western wall for 40 rupees if you wish). Anyway head upwards. You can bomb the left wall for 40 rupees, and killing the Stalfos opens the other door. Go through it.
Go down the stairs to B1. Go through the door directly to the right (the wall to the left hides 40 rupees if you want them) and kill the tentacles to proceed. In the next room, lift the right-hand pot for aSmall Key. Go down the stairs and through the door.
In this next room lift the central pots to restock your arrows. In the next room use arrows or pots to kill the Eyegore for aSmall Key. Open the door, kill or avoid the two Eyegores and again collect the arrows. By now you should have 30, so unlock the Boss Door and go in. Shoot the red Eyegore to kill it (you can throw pots at the other if you wish, but they won't kill the red one). The left-hand wall hides 40 rupees if you want them.
In the next room lift the top-left pot for aSmall Key. Open the chest for the Pegasus Boots. You can now run everywhere. Unlike in The Legend of Zelda: A Link to the Past you can even change direction when running.
If the clock has reached or passed you'll notice an infinity symbol (∞) beneath the arrow icon. This means you have unlimited arrows, so you can shoot at the bosses without worrying about running out.
Now unlock the door and fight the Armos Knights. They move in two simple patterns (a gradually expanding circle, then a horizontal charge from the top of the screen to the bottom, then the circle again) so it is fairly easy to predict their movements. You can defeat them using the bow or by charging at them with the Pegasus Boots. It takes two hits to destroy one of the knights. They will keep doing these patterns until only one remains. The final one will turn red and start jumping towards you, trying to squash you. He takes three hits to defeat.
Collect the Heart Container andTablet and you can leave the dungeon.
