Freeze two Zeelas to perform an 'Enemy Stuck Moonfall' in order to clip through the Power Bomb blocks. Position one Zeela upside down on a ceiling, and another below it on the ground. The global Zeela paired with either the lowest Zeela, or the other perimeter Zeela can be used, but freezing them together is the hardest part. Freezing one and then unequipping Ice Beam to dispel the ice effect or manipulating the camera can be used to synchronize them. If the moonfall is initiated immediately after freezing both enemies, it is possible to gain enough speed to automatically clip through the enemy and the floor; in this case, hold an angle button to buffer a pose change. Alternatively, and more easily, when one of the enemies is about to thaw, hold backward in order to move forward and fall off the enemy with a buffered turnaround, which will clip through the floor without needing as much fall speed. From directly on top of the Power Bomb blocks, no pose change is needed. Two Super Missiles can speed up the Zeela setup greatly by knocking them off of the wall.

Break exactly the lower-middle-right and top-right Bomb Blocks, leaving the upper-middle-right and bottommost Blocks intact. Clear all enemies before starting. Unmorph while on the top block to begin the Moondance. Exactly 145 moonfalls after clipping into the bottom block (321 total), wiggle out to the left. The next moonfall will clip Samus down two tiles. Re-enable Screw Attack and moonfall to break the right side blocks, then use Grapple again to become unstuck.

Normalized movement through the room can be used to manipulate the Sm. Dessgeegas and do this strat reliably without heat protection. The following is one way to do this; other approaches may also be possible. Before entering the room, damage down to between 127 and 159 energy, and unequip Speed Booster if it is collected. Position one pixel away from the door in the previous room. Hold angle-down (and optionally dash), enter the door transition, then hold shot while continuing to hold forward, angle-down, and dash. The shot block will be destroyed by the buffered shot. Continue holding right and dash to run under both Sm. Dessgeegas. After running under the second one, stop for a moment to prevent it from scrolling off camera. Morph, roll all the way against the right wall and quickly lay a Power Bomb. Move slightly to the left to avoid being bounced by the Power Bomb explosion. As the Sm. Dessgeega approaches, roll under it to the left to avoid being hit. Roll back to the right to collect its Power Bomb drop (which should be a ground level) and return to where the Power Bomb was laid, in time to perform the Crystal Flash inputs.

Only requires a runway of 6 tiles (with no open end) in the adjacent room. Perform an air ball while against the ceiling to make it up and through the morph tunnel. If the runway length is minimal, the aim-down input must be delayed a bit (rather than buffered through the transition), so that Samus moves at a slightly higher horizontal speed for longer.

Requires a runway of at least 4 tiles (with no open end) in the adjacent room. Use a Cross Room Jump into Water followed by a delayed Momentum Conserving Turnaround to reach the Morph tunnel above. Climbing the Left side of the center hole will run into an unavoidable Sciser that can be passed through by Morphing. Crossing to the right from the left door requires slightly more runway and takes a more precise turnaround. Samus must also stay near a side of the center hole to reach the Morph tunnels.

This underwater walljump is very long. Some jump assistance, cross room jump, or a flatley jump from the door frame is needed to get to the first overhang.

In the previous room, gain max run speed without Speed Booster equipped, requiring about 7 tiles of runway (obtaining an extra run speed of $2.0). After the transition, jump to slightly less than full height, performing a lateral mid-air morph just early enough to avoid bonking the ceiling Grapple block. Pause to equip Speed Booster before bouncing on the first Grapple platform; this provides a boost in the bounce height to be able to make it to the Grapple platform below the top door.

Gain blue speed by running right-to-left on the 20-tile runway below the items. Then use Space Jump to carry it across the top of the room to break the bomb blocks. To cross the room most easily, blue speed can be gained with low momentum by pressing pause, running a few tiles, stuttering just before the pause hits, disabling Gravity suit, continuing to run left, then re-enabling Gravity suit before jumping. Alternatively, a regular shortcharge can be used in combination with either HiJump or a precise amount of extra run speed ($2.0 or $2.1), to cross the room at higher speed.

Requires a runway of 7 tiles (with no open end) in the adjacent room. Requires two precise inputs of jumping through the doorway and a short aiming down press before hitting the ceiling. Damage boost off of the right Evir in order to land on the first pillar. With Ice, instead freeze the Evir to land on it and avoid the damage. When entering the room with a bad jump, it is possible to perform a midair wiggle to get back to the door platform.

Gain momentum in the room to the left, then jump at the edge of the runway in this room in order to jump off of the sand and land on the first pillar. Requires a runway of 7 tiles (with no open end) in the adjacent room, and killing the second Evir with a quick super or two plasma hits (note that the particle despawns as the Evir dies).

Gain momentum in the room to the right, then jump immediately on entry in order to land on the first pillar. Jumping too late will likely put Samus into the pit. Requires a small runway of only one tile or less in the adjacent room. Jumping before the door transition will set Samus straight into an Evir projectile, knocking her into the sand.

Clears obstacles: A

Gain momentum in the room to the left, then jump in this room in order to land on the first pillar. Ensure that Speed Booster is disabled. Requires a runway of only approximately 0.5 tiles in the adjacent room. Perform an air ball before hitting the ceiling in order to land on the first pillar.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": false,
    "minTiles": 1
  }
}

Requires:

"canLateralMidAirMorph"
"canCrossRoomJumpIntoWater"
"HiJump"
"canPlayInSand"

Gain momentum in the room to the left, then jump after entering this room in order to land on the first pillar. Ensure that Speed Booster is disabled.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": false,
    "minTiles": 5
  }
}

Requires:

"canCrossRoomJumpIntoWater"
"canPlayInSand"
"canCarefulJump"

Gain momentum in the room to the left, then jump in this room in order to land on the first pillar. Ensure that Speed Booster is disabled. With a short runway of 4 tiles (with an open end) in the adjacent room, it is required to jump as late as possible at the edge of the runway in this room. Shrinking Samus' hitbox before landing makes the jump a little easier.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": false,
    "minTiles": 4
  }
}
