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.

Turn off Gravity and HiJump to jump directly here.

Requires:

"canSuitlessMaridia"
"canDisableEquipment"

Needs a runway of 7 tiles with no open end in the adjacent room, to get enough height. This is a peak of height with speed booster, no hjb, while underwater. Jump before the transition with SpeedBooster off and then SpeedBooster back on after reaching the ceiling and Morphing.

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": true,
    "minTiles": 6.4375
  }
}

Requires:

"canLateralMidAirMorph"
"canDisableEquipment"

  "or": [
    {

    {
      "and": [
        "Plasma",
        "canTrickyJump"
      ]
    }
  ]
}

Requires running 7 tiles with no open end in the adjacent room, as this is a peak in jump speed. Run with Speedbooster off, and turn it on after entering the room.

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": true,
    "minTiles": 6.4375
  }
}

Requires:

"canDisableEquipment"
"canCrossRoomJumpIntoWater"

Jump and mid-air morph. This is much easier with Gravity and HiJump turned off.

Requires:

"canSuitlessMaridia"
"canMidAirMorph"
"canDisableEquipment"

Jump and mid-air morph. This is much easier with Gravity and HiJump turned off.

Requires:

"canSuitlessMaridia"
"canMidAirMorph"
"canDisableEquipment"

This can be done by turning off Gravity and HiJump to do a mid-air morph through the morph tunnel.

Requires:

"canSuitlessMaridia"
"canMidAirMorph"
"canDisableEquipment"

This can be done by turning off Gravity and HiJump to jump over both spike pits.

Requires:

"canSuitlessMaridia"
"canDisableEquipment"
"canCarefulJump"
{
  "or": [
    "Gravity",
    "HiJump",
    "canSpringBallJumpMidAir"
  ]
}

This can be done by turning off Gravity and HiJump to jump over both spike pits.

Requires:

"canSuitlessMaridia"
"canDisableEquipment"
"canCarefulJump"

The lenient version requires a runway of at least 5 tiles (with no open end) in the adjacent room. This is easier without Speed Booster and requires disabling HiJump.

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": false,
    "minTiles": 4.4375
  }
}

Requires:

"canCrossRoomJumpIntoWater"
"canDisableEquipment"

Requires a runway of at least 2 tiles (with no open end) in the adjacent room. This is typically easier without Speed Booster depending on the exact runway length and requires disabling HiJump.

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": false,
    "minTiles": 1.4375
  }
}

Requires:

"canCrossRoomJumpIntoWater"
"canMomentumConservingTurnaround"
"canTrickyJump"
"canDisableEquipment"

It is possible to jump to the top door using a runway of just one tile with Speed Booster and no HiJump. Requires a last-frame jump and down press that is late but not immediately before the turnaround. With a second-to-last-frame jump it is still possible but more precise.

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": true,
    "minTiles": 1
  }
}

Requires:
