Go downward and to the left in the water and bind to the large boulder, and swim to the right to pull it out of the way. Go through the opening where the boulder was.

Go down and to the left, to where there is another boulder. Bind to it and pull it up and to the right, and set it on the ledge. Then swim downward through the opening where it was. Swim in front of the bubbles to refill your dive meter, then try to swim to the right. There will be a cutscene.

Swim Away from the Whirlwind

Swim to the right to stay away from the whirlwind. You can press R to spin, which makes you go a little faster. Stay in the bottom half of the area, where the path is straighter, but beware of the Sand Crab and Tangler. Swim in front of the bubbles to refill the dive meter.

Continue swimming to the right. There are some wooden boxes in the way. Create a Bombfish to destroy them (press R to spin if the Bombfish doesn't activate). You don't get hurt by Bombfish that you create, so there is no need to swim away from it. Then keep going to the right. Avoid the Biris and the Sea Urchin, and swim in front of the bubbles.

There is a boulder in the way, so bind to it, then push it to the right, and release it as soon as it's past the edge of the ledge. Swim toward the upper-right, and go up the ladder.

Create a water block to get out of the water, then go up the ladder.

Go to the east wall and dive downward, then go east to go through the hole in the bars. Defeat enemies as needed. You want to reach the northwest corner of the room, and there are multiple ways to do so. You can either break the wooden box underwater in the north wall and go through, then use water blocks to go up the steps on the left, or you can use water blocks to reach the northeast ledge, and use water blocks to reach the wooden walkway along the north wall, then go west and use water blocks to go up the stairs. Then open the chest to get 50 rupees.

Then use water blocks to go east onto the wooden walkway, and create water blocks on top of the rope so you don't have to worry about falling off. Go to the wooden platform south of the rope, then go west through water blocks across the west rope. Go up the stairs at the end.

Defeat the crabs above and below the water, and the doors will open. Go through the northwest door.

Go down into the water, swim south of the torch, then bind to the torch and hold the B button to bring it up above the water. Put it down on the ground. Then use an Ignizol or Brazier echo to light the four torches. The door will open. Go through.

Step on the switch to activate another water spout in the main room. The central jet of water is going high enough that you can reach the bridge above it.

Get the Big Key

Fall down the hole in the northeast corner of the room. You end up in the underground area where you were earlier. Go up the ladder on the right.

Go to the water in the middle part of the room and stand in the jet of water to be pushed up to the bridge above.

Then go to the right and use a Bombfish on the wooden boxes or just bind to them to pull them out of the way. Then go through where the boxes were, and go up. Swim in front of the bubbles, then keep going up to reach the next room.

You have to defeat a lot of underwater enemies. Try using an underwater monster echo, such as a Chompfin, to defeat some of the enemies. You can also switch to swordfighter form to fight them. After they're gone, the door will open. Go underwater to go through the door in the west wall.

Defeat the two Bio Deku Babas, then create a heavy echo, like a boulder, on top of the button. You will need to float slightly higher than the level of the button to make sure that your echo has enough room to be created. There will be a cutscene.

From the ledge, you can create boulders to sink down into the water. You can walk across them to avoid getting pushed south. Be sure to jump on top of pieces of wood so they don't push you south. Keep making boulders to walk north. Beware of the Tektite to the north. Use a trampoline or other echo to reach the ledge. Go through the door.

There are many glowing switches in this room. You have to hit them all to close their eyes. You can create wooden boxes in the water to help you reach the switch on the middle platform and press R to spin and hit that switch. Then you can use a monster echo, or an arrow while using swordfighter form, to hit the northeast switch. You can create an underwater monster echo and hold ZL to target the underwater switch. You can use a flying monster echo or an arrow in swordfighter form to hit the southwest switch (use wooden box echoes to reach it if needed).

Then go to the northern ledge where the closed door is. Use water block echoes to reach the left ledge. Make sure the first water block is on top of the ledge in front of the door. Then you can create an echo, such as a rock or a Caromadillo, and pick it up and throw it at the boxes to break them and hit the switch. The door will open. Go through.

You need to defeat the Tektites in this room to open the door. Use a monster echo or swordfighter form to defeat them. Then go through the east door.
