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. The cross room jump requires an adjacent runway of 3 tiles (with no open end) with HiJump disabled. Perform a turnaround just before hitting the ceiling.

Jump towards the door with HiJump equipped. A Flatley style jump can position Samus over the edge of the ledge, closer to the door. Turning around while facing down, just before touching the ceiling, is another way to move Samus a few pixels closer to the 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.

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.

Run and spin jump from the platform in the room below, gaining horizontal speed but without bonking the door frame.

Do a low spin jump and press against the right side of the door frame. Wall jump as low as possible, jumping as soon as possible after moving away from the wall. Immediately turn back to the right and try to press against the door frame again before the transition, while maintaining spin. After the transition, typically a momentum-conserving turnaround is needed to avoid bonking.

Dev note: The transition likely connects to Pants Room making this strat not likely to be useful. This can be done with a slightly shorter, closed end runway.

Use a 2-tap shortcharge and jump into the room with a last-frame jump, breaking the bomb block with blue speed, and making it all the way through the top door. Use angle to break spin, and do a momentum conserving turnaround either on the same frame or one frame later; this first turnaround should be done early enough that the turnaround is complete by the time Samus clears the two-tile passage in the middle of the room. Do a second momentum conserving turnaround must be done somewhat late, and by switching from holding left to holding right one frame later (a perfect 'boomerang'). Shoot open the door, and use a third momentum conserving turnaround on it as it opens.

Lower run speeds are generally better, as long as the extra run speed is at least $3.4. this gives up to a 7-frame window for the first turnaround, and typically a 4-frame window for the second turnaround if the first turnaround is done early enough. A perfect boomerang is always required for the second turnaround, regardless of where in the window it is done. It is recommended to buffer the spin break, by holding angle (up or down), jump, and forward through the transition, then switching from forward to backward, with at most 1 frame of neutral in between, while still holding jump and angle.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it all the way through the top door. Ideally, gain speed using between 13 and 13.5 tiles of runway (with an open end). Longer runway lengths can also work, up to 17 tiles, but will make the trick somewhat more precise. Use angle to break spin, and do a momentum conserving turnaround either on the same frame or one frame later; this first turnaround should be done early enough that the turnaround is complete by the time Samus clears the two-tile passage in the middle of the room. Do a second momentum conserving turnaround must be done somewhat late, and by switching from holding left to holding right one frame later (a perfect 'boomerang'). Shoot open the door, and use a third momentum conserving turnaround on it as it opens.

The optimal amount of extra run speed is $3.4 or $3.5, by using 13 tiles of runway or about a half tile more; this gives a 7-frame window for the first turnaround, and typically a 4-frame window for the second turnaround if the first turnaround is done early enough.
