After you have progressed further, you’ll finish a task, go through the open door, and move downward. You will pass some murals before reaching a new door.

There is a Block and a Platform right next to it. Just put the Block on the Platform to open the path. Go through that door and then head through the flap to find one more door.

Finding the Hidden Switch

To open this door, you need to move the large Yellow Rectangular Blocks. They are hiding a Switch. You cannot press this while you are in your boat in Planet of Lana II.

Once the Yellow Rectangular Blocks are out of the way, head to the Air Pocket above and hop out of the boat. Swim down to hit the Door-Opening Button by hand, then get back into your boat.

Solving the Hexagon Block Puzzle

Past the door, you will see a Hexagon Block that looks similar to the others. You need to reach it. Go up and around the area until you find a small Elevator Shaft.

Grab the Hexagon Block and pull it out of the shaft. Move it to the side so the elevator can rise.

When the elevator reaches the top, put the Hexagon Block back onto it. Quickly move back around to the left as the elevator starts to go down in Planet of Lana II.

If you are fast enough, you can slip through the gap while it is open. From here, just keep moving forward through the flap. The rest of this part is simple. Just swim toward the surface when you see the chance.
