With only 1 tile of runway in the other room, Samus should ideally start on the last pixel of runway with X subpixels of $3FFF or less. Run toward the door, releasing forward for exactly 1 frame and pressing it again on the last possible frame before the transition. Starting with X subpixels of $7FFF can also work (e.g., by simply backing against the door ledge, then jumping and turning around mid-air); in this case, Samus must advance 1 or 2 pixels with an arm pump before the transition (e.g., firing a shot or pressing and/or releasing an angle button), and the shinecharge will be gained slightly further away from the door. After gaining the shinecharge, continue holding forward in order to make Samus stand. Then turnaround spin jump back toward the door, and continue spin jumping to reach the transition with a shinecharge. Alternatively, with greater difficulty but saving some shinecharge frames, after performing the turnaround spin jump, briefly moonwalk back, then retain momentum by boomeranging forward (switching from pressing backward to pressing forward on the next frame), and arm pump to reach the door quickly.

Ideal subpixels ($3FFF) can be achieved using one of several methods: 1) press forward against the door ledge (or a wall aligned with it); jump, and while mid-air, tap forward for exactly 1 frame to land with subpixels $BFFF, moonwalk back for exactly 1 frame to end with subpixels $3FFF. 2) press forward against the door ledge (from a platform below, assuming one exists) turn around (while on the ground), and moonwalk back two pixels, then jump and mid-air turnaround onto the ledge; if Samus jumped from the correct pixel but does not land on the ledge, then it was needed to moonwalk back 1 more frame; in this case it is possible to retry by doing a mid-air turnaround back onto the platform, and moonwalking back for 1 frame. 3) if X-Ray is available, press against the door ledge (from a platform below, assuming one exists) turn around (while on the ground), then jump and mid-air turnaround toward the door, and use X-Ray to turnaround in place away from the door; repeat this sequence 3 more times: jump, mid-air turnaround, X-Ray turnaround; then do one more jump and mid-air turnaround, high enough to land on the door ledge, and Samus should be in the correct position with subpixels $3FFF.

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.

Use two snails to perform an 'Enemy Stuck Moonfall' to bypass the bomb blocks above the middle left door. Position one snail on the above door shell, and the second above the corner of pipe below. Samus will clip through the lower snail, taking damage, then continue through a segment of pipe where the crumble blocks can be reached. Facing both snails during the moonfall while positioning Samus for the clip can be precise. Depending on the exact heights of the snails, it may be necessary to pose change while clipping. Damage from the snail can be avoided by shooting the snail at a precise time: the water cycle or Samus' air bubbles can be used as a cue for the timing.

Crouch on rightmost pixel of the ledge to the left of the door, jump then move over quickly without spin jumping. The timing for the forward press needs to be between 0 and 5 frames after pressing jump (a 6-frame window). Samus's subpixel position is important: X position needs to be at least $64.4000, this is the rightmost 75% of the rightmost pixel. Morph provides an easier setup. From below the ledge, press left against the wall, jump, mid-air morph, and tap left to move slightly onto the ledge.

Use two snails to moonfall down through the pipe to the section below. The snails should be easy to align, with one on the floor and another on a ceiling 4 tiles higher. Shoot the lower snail after Samus has enough fall speed in order to avoid taking a snail hit. There is a small set of frames between these two, in which Samus will fall out of bounds. With Gravity, there is approximately a 5 second fall, with a 15 frame window. Suitless, there is approximately a 17 second fall, with almost a full second window - this is approximately 8 sets of bubbles out of Samus' arm. With blue suit no timing is necessary, with or without Gravity. Samus will clip automatically once enough fall speed is reached without taking damage, killing the bottom yard.
