Floor 14 (2)

Follow the halls until a Blue ChuChu appears. Allow Phantom Zelda to defeat it.

Continue forward and defeat another Blue ChuChu.

You will encounter a sand pit. Link can walk across sand, but Phantom Zelda cannot due to her weight.

Instruct Phantom Zelda to stand on the ground switch on her side of the sand pit.

Cross the sand pit with Link and stand on the switch on your side. This will create a bridge for Phantom Zelda.

Guide Phantom Zelda across the bridge.

Move east and you will see spikes on the floor. Have Phantom Zelda cross them.

Instruct Phantom Zelda to stand on the red, glowing tile.

Have Link follow the rest of the hall and stand on the same tile on your end. This will switch Link and Phantom Zelda's positions.

With Link in position, take the sword from the left fish head and place it into the right fish head. This action will open the door to the upper level.

Retrieve Phantom Zelda, then proceed upstairs.
