Part 21

Head to Thieves' Town and save your game. Go north to the two black towers.

Examine the locked door on the left tower. You will need to complete a song to gain entry. The correct answers are: "A Narrow Path", "Really Despair", "To Thievin'".

After the guard leaves, go north across the walkway and enter the room on the left. Grab the chest containing a Purple Rupee and return to the entrance.

Go left and enter the next room. Merge with the wall and enter the cell to the north to find a chest with another Purple Rupee.

Go left to find a crystal in the center of the room. Hitting it raises some bars and lowers others. Hit the crystal and merge to the southwest corner.

You will find two statues and arrows shooting from the north. Move one statue north of the arrow's path and place it on the switch. Push it up twice, then quickly turn around and block the arrow. Repeat this process.

Move the other statue out of its cell, hit the crystal again, and place it on the switch north of the crystal.

Enter the cell where you previously found a Purple Rupee and step on a third switch to open the door to the north.

In the next room, defeat the Zazak (these lizards chase Link and deal 2 Hearts of damage; the Fire Rod works well against groups).

Go north to the next room and defeat the rats. You will see a metal path on the left and a wooden path on the right. Drop down from the wooden path to floor B2.

Get the chest on B2 for another Purple Rupee. Drop down again.

You will see a crystal on the left that changes the direction of the conveyor belts. Hit it if you wish.

Go all the way south to the next room. Here you will encounter Sluggulas (which leave slime and bombs in their trails, dealing 1 Heart of damage) and Bawbs (which chase Link and explode, dealing 1/2 Heart of damage; it's best to avoid them as they continuously spawn).

Go up the stairs, merge with the wall at the end of the conveyor belt, and hit the crystal at the end of the path.

Head back downstairs and hit the Bawb. Once it transforms into a bomb, grab it and throw it onto the conveyor belt so it hits another crystal, which opens the door.

Go through the opened door into a trap room. Hitting the crystal on the left side will open up the floor, causing you to fall.

Go right into the next room to find stone plaques. Merge with them to collect Hearts and Rupees. Go right to find a chest containing Monster Guts.

Return to the previous room and go north.

In this larger room, merge with the right wall and enter the upper cell to find a Stalfos and a chest containing a Compass.

Merge into the lower room and speak to the Thief Girl. Step on the switch to open the door on the left side of the room.

Go through the door and merge into the room to the north. Use a Bawb to break open the cracked wall to the north. Go inside and proceed down the left side of the wall.
