DUNGEON: Dancing Dragon Dungeon
Dancing Dragon Dungeon is a dragon-shaped mine shaft of doom. You'll find the treasures in here have been heavily guarded with monsters and danger to discourage adventurers.

However, the next essence resides in here, and the only way to find it is to face the challenges this trouble-filled dragon holds.

Waterlogged and danger-ridden
The first room, as are many others here, is flooded with water. There is a locked door to the right, so swim over to the left to enter the next room.

This room has a chest you can easily reach: simply push the block two spaces left from it down. You'll find 10 Bombs.

With those extra bombs, ignore the Shrouded Stalfos and hop in the mine cart.

As you ride the mine cart, you'll pass a switch. Don't hit it until you round the curve. You'll switch the tracks, but still head north.

Once again, ignore the enemies and go east to spot a cracked wall. Plant a bomb right by it and head into the uncovered room.

Eight switches, nine pots, and one small key
Here is a simple puzzle: activate all the switches at once. However, there are 8 switches and 9 pots to use. Two aren't needed, but to make things easy, follow this solution:

You'll earn a Small Key as a reward. Now, take it and unlock the door in the first room.
