After you pass the murals and reach the next area, swim to the top of the water. Leave your boat and climb up using the Yellow Bars and the Rope. You will find the Girder Puzzle waiting there.

Getting the Power

The goal is to send electricity to an Underwater Button. First, dive back into the water and swim as far right as you can. You will see a Jellyfish. Touch it so it floats up and hits the Girder, which gives it an electric charge in Planet of Lana II.

Moving the Girders

Go to the middle platform where a Switch sits between two Generators. This Switch moves the Girders hanging from the ceiling, but only if they are lit up.

You can use Mui to stop them from moving. If Mui powers the Right Generator, the Right Girder stays still. If Mui powers the Left Generator, the Left Girder stays still.

Connecting the Current

Tell Mui to use their power on the Right Generator in Planet of Lana II.. Flip the Switch to move the Left Girder until it touches the piece sticking out of the water. Next, have Mui switch to the Left Generator.

Use the Switch to pull the Right Girder over to the electrified one on the far right. This sends power through the whole line. Once that is done, dive back down and hit the Underwater Button to open the Door.
