Plasma Beam Search

Walkthrough: Head back to where you originally fell through the floor, but this time use the Phase Drift to get past this area. Grapple Beam the red orb to avoid the section for later backtracking, and then head to the nearby Save Station. There should be a weak point to the left that should lead to another area, but, again, there isn't anything to do there just yet. So, instead, use the Phase Drift to get past the wall fire, and then take the elevator up.

For a few purposes, go through the first door you find. Use the Phase Drift to get by the lasers, and then enter the next two sets of doors to find the next Teleportation Statue. Dropping below into the bottom door with bring you to another Morph Ball Maze followed by another red orb. Pull the red orb to the right side, and then drop down and destroy the second visible block. Head back up and pull the left side to earn access to the next room. Inside you'll find and obtain the Plasma Beam, the same that can open up green glowing doors (not green barrier doors).
