Back outside again, head south 3 screens and enter the cave you see there.
Show the Letter to the Old Woman, then buy some Water of Life (whichever one you can currently afford is fine).
Then, go east 3 screens and south 1 screen, and enter the cave to play a Gambling game (if you don't have 10 rupees, fight some enemies to get that much). Play until you have about 60 rupees, then leave and head east 5 screens, which should be the first screen with the Leevers.
Go north 4 screens and west 1 screen, then use the Whistle there to reveal hidden stairs. Go down them and choose the Heart Container, giving you 7 total.
After that, go north 1 screen, east 3 screens, then take the north path north another screen. Continue east 2 screens and walk through the north wall to the upper-right corner of the overworld map. Enter that shop and buy Bait for 60 rupees, then leave there.
Go south 1, west 2, south 3, west 1, and north 1. You should be at an area with a pond in the middle.
Play the Whistle to drain the pond, revealing stairs; go down the stairs to enter Dungeon 3.
Dungeon 3
Upon entering this dungeon, head north to the next room. Defeat the red Goriyas there, then continue north to the following room.
There, defeat the electrical Ropes, then take the Bombs and go north to the next room.
In this room, defeat the blue Goriyas while avoiding the fireballs being shot from all four corners. Take the Map, then continue to the following room.
Defeat the Stalfos and take the Key that appears, then go north to the next room.
Here you'll find a Goriya blocking your path, so give it the Bait and it'll disappear. Now, unlock the north door and enter the next room.
Defeat the red Goriyas here, then take the Metal Boomerang to replace your old wooden one.
After that, backtrack by going south through 5 rooms. When you get to that 5th room, unlock the east door and enter that room. You'll face 3 Dodongos here as the dungeon's bosses, so read the
Enemies section if you need help here.
After that, take the Heart Container and unlock the south door, then continue into the next room.
In this room, defeat all the Wallmasters, then take the Compass and push the middle block in the right row to reveal some steps. Go down them and through the passage to the following room.
There, defeat the red Goriyas and take the Key, then go through the north door to the final room.
In that room, take the Triforce piece and you'll be sent out of this completed dungeon.
NEXT: Dungeon 4
