Precise Stutter Shinecharge, Leave Shinecharged (5-tile runway) (Extreme)
Crab Shaft
From: 1
Left Door
To: 1
Left Door

With a runway of 5 tiles (open end) in the other room, the ideal timing for the stutter is to release forward for 5 frames, and repress forward on the last possible frame before the transition. Other timings can work, but will gain the shinecharge further from the door, leaving fewer shinecharge frames remaining. 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.

Precise Stutter Shinecharge, Leave Shinecharged (4-tile runway) (Extreme)
Crab Shaft
From: 1
Left Door
To: 1
Left Door

With only a runway of 4 tiles (open end) in the other room, the ideal timing for the stutter is to release forward for 4 frames, and repress forward on the last possible frame before the transition. It also works well to release forward for 3 frames and repress on the last possible frame. Other timings can also work, but may gain the shinecharge further from the door, leaving fewer shinecharge frames remaining. 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.

Precise Stutter Shinecharge, Leave Shinecharged (3-tile runway) (Extreme)
Crab Shaft
From: 1
Left Door

With only a runway of 3 tiles (open end) in the other room, the ideal timing for the stutter is to release forward for 3 or 4 frames, and repress forward on the last possible frame before the transition. Other timings can work, but will gain the shinecharge further from the door, leaving fewer shinecharge frames remaining. 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.

Precise Stutter Shinecharge, Leave Shinecharged (1-tile runway) (Insane)
Crab Shaft
From: 1
Left Door
To: 1
Left Door

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.

G-Mode Ice Clip, Door Lock Skip (Insane)

To get a crab at the top of the room, use a Super to knock off the central crab and use Ice to climb it to the top of the room.

Samus must shoot the Super while the crab is on a block next to the door, not on the door itself.

Side Platform Cross Room Jump (Very Hard)
Crab Shaft
From: 1
Left Door

Platform Below Top Door

Use a platform below the door in the other room to jump through the door while aiming down, carrying upward momentum into this room. Hold down and back through the transition, to perform a momentum-conserving turnaround past the corner. In cases where the previous room has an extended door ledge obstructing the exit, the turnaround may need to be initiated before the transition, to avoid bonking the ceiling of the door frame.

Side Platform Cross Room Jump, Bomb Into Spring Ball Jump (Insane)
Crab Shaft
From: 1
Left Door
To: 4
Platform Below Top Door

Use a platform below the door in the other room to jump through the door while aiming down, carrying upward momentum into this room. Hold down and back through the transition, to perform a momentum-conserving turnaround past the corner. Perform a mid-air Spring Ball jump, timing a pause to hit soon after the mid-air jump. Unequip Spring Ball, lay a Bomb about half a tile below the peak of the jump. Press pause at the peak of the jump, tp reequip Spring Ball immediately after Samus is boosted by the bomb. Buffer a jump out of the unpause, to get a second Spring Ball jump and make it up.

Very Precise Stutter Water Shinecharge (Insane)
Crab Shaft
From: 1
Left Door
To: 5
Middle Right Shinecharged

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.

Correct subpixels can be achieved using one of several methods: 1) press 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 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.

Samus must shoot the Super while the crab is on a block next to the door, not on the door itself.

To get a crab at the top of the room, either use a Super to knock off the central crab, or bring the bottom global crab by breaking the shot block in the middle of the room and using Ice to climb it to the top of the room. Shoot a Super as the crab crawls near the top door, then freeze it mid-air and use it to clip up past the door shell. Without Morph and X-Ray, Samus must shoot the Super while the crab is on a block next to the door, not on the door itself. With Morph and X-Ray, knock the crab off while on the ceiling one tile lower than the doorshell for a one-frame freeze window. This has a two-frame window with Gravity or HiJump.
