Overload PLMs using the scroll block at the top of the stairs next to the bomb blocks. A long series of precise bomb jumps and enemy manipulations are required to reach the top without taking a hit.

Entrance condition:

Enter the room with a very specific run speed to jump from the door, squeeze by the ceiling, and land a speedball perfectly in the tunnel to break the Bomb block.

A long series of precise bomb jumps and enemy manipulations are required to reach the top without taking a hit or unmorphing. Overload PLMs using the scroll block next to the bomb blocks at the top, allowing passage through them by making them become air.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "any",
    "morphed": true
  }
}

Requires:

{

Perform 176 moonfalls using the respawning shot block: after each moonfall, destroy the shot block (aiming up with angle up + angle down) and press forward to stand up; wait for the shot block to respawn before performing the next moonfall. On the 176th moonfall, Samus will sink a tile into the floor. Use Grapple to stand back up and perform 146 more moonfalls using the respawning shot block. On the 146th moonfall, Samus will sink 2 tiles into the floor. From here, continue using Grapple to stand up and perform another 145 moonfalls, but now without needing to use the shot block. After clipping 2 tiles into the floor with the 145th moonfall, unequip Grapple and perform a final 146th moonfall from 2 tiles deep in the floor to clip past 3 more tiles and reach the bottom of the room. Note that exact counting needed here: losing count and performing the 146th moonfall from the surface would cause Samus to clip 3 tiles into the floor and be stuck in a crouched state, unable to stand back up with Grapple nor able to perform the final moonfall needed to clip the rest of the way down; conversely, performing a moonfall early from 2 tiles deep, before gaining enough speed, will result in Samus only clipping down through a total of 4 tiles, again resulting in a softlock. This strat takes approximately 45 minutes to execute.

Be sure not to lure the first crab on the right wall until the slow global crab is near. Freeze the crab coming down as a platform to stand on to jump onto the frozen global crab on the right. Near the end, use the global crab to get onto the top left corner of the room, then jump towards the walkway leading to the door.

Use a double spring ball jump to reach the Speed blocks below the items while chaining temporary blue. Perform a spring ball jump and immediately unmorph and continue holding up, to break some of the Speed blocks while passing up through them. Leave one of the bottom Speed blocks unbroken to use as a platform. The top speed blocks will respawn; clip through them either using a snail clip with X-Ray or a Crystal Flash clip; In the case of a Crystal Flash clip, menu to Grapple before the Crystal Flash ends and mash shoot while holding down.

Use double spring ball jumps to reach the top-right of the room with temporary blue.
