It is possible to cross the spike pit with spring flings and two spike hits. Pause then jump just before the fade out ends and turn Spring Ball off in order to get more horizontal distance at the start and avoid one spike hit. Turn Spring Ball off and on again while jumping on the spikes to get across to avoid another.

Roll through the item to overload PLMs, then go down through the speed blocks and exit G-mode to collect the item. Note that if the item has already been collected, Samus can overload PLMs with Grapple.

With Morph and Grapple, quickly grapple to then release grapple on the grapple blocks a few times until they stop working. Be careful not to fall into the spikes.

Gain temporary blue at the end of the runway. Then spring ball bounce through the tunnel. Press pause while exiting the tunnel. If Samus bounced far enough right, disable spring ball (a 'spring fling') to make it directly onto the item pedestal, chaining temporary blue from there. Otherwise, unpause without disabling spring ball, and chain temporary blue by landing on the ground.

Use a Power Bombs to kill the first three hoppers, or carefully dodge them by quickly rolling between the first two tall flowers and waiting for the hopper to jump over Samus. The middle hopper can be killed safely with many Bombs by staying on the top left of the raised ground, without overhanging or the hopper can hit Samus. Alternatively, lure and spring ball jump past it. Killing the bugs in their pipes is possible without getting hit, or use spring ball to jump past them. Once the bugs are killed once they will stop respawning. The last hopper can be carefully killed with Bombs, or killed with a Power Bomb, or dodged and lured off the edge. IBJ, bomb boost spring ball jump, or HiJump Spring Fling up to the pipe.

Note that one Power Bomb can be saved with a Spring Fling from the lower item pedestal; pause and just before the screen is fully black, jump, disable Spring ball, then buffer right on the unpause. Another can be saved by carefully jumping out of this morph passageway. Kill or carefully dodge the Sidehoppers at the top, then Power Bomb boost Spring Ball jump up to the top left door and exit G-Mode.

Climb the room while avoiding the Reo and the camera scroll block against the wall in front of the off-screen Super tunnel. IBJ from the lower hopper pit, or with HiJump, perform a Spring Fling from the right pillar by jumping immediately before the pause finishes and turning off Spring Ball, quickly pausing again and turning Spring Ball back on can help as well.

Fully overload PLMs with the item before climbing the room. The hardest part is getting past the Reo without Power Bombs, if it is stuck in the stairwell just above the door. Either manipulate it until it can escape, get it stuck swooping in the top right corner of the stairwell then kill it with Bombs, or avoid it entirely, and go up through the crumble blocks to the left after manipulating the Sidehoppers to be off-camera at the right of their pit. Avoiding the top Sidehoppers without Power Bombs can also be tricky; if starting at the top of the room, it may help to lure them to the left before going down the room. For safety, it is also possible to lure the hoppers to the left from below with several IBJs or HiJump and Spring Ball.

X-Ray climb until Samus is a little over halfway off screen; the position is not precise. Face right, then do a turnaround buffer spin jump into a Spring Ball jump to reach the ledge. The pause input can be pressed at the same time as the turnaround. It helps to do an airball to gain horizontal speed. The jump input after pausing should not be buffered, in order to allow a little time for the spring fling horizontal speed to take effect.

Use a Crystal Flash to refill reserve energy. If Golden Torizo is alive, perform the Crystal Flash in the left corner of the room; otherwise it can be done near the door. Then use heat damage to trigger an R-mode forced standup near the crumble blocks with upward momentum, in order to clip up through them. Several different combinations of items and techniques can make this possible: 1) Space Jump, with a mid-air morph (not required but makes it easier), 2) HiJump and a mid-air Spring Ball jump, most easily by equipping both HiJump and SpringBall during the pause, 3) A walljump into Spring Ball jump, equipping Spring Ball soon after the wall jump into order to gain horizontal speed before the mid-air jump. 4) HiJump and Speedbooster, running and jumping into a mid-air morph, In every case, precise timing is needed to be in the correct location when reserves trigger, just below the crumbles but without bonking them. Having less upward momentum can provide more lenience for timing the forced standup clip, though if Samus' momentum is not enough to make it onto the ledge then a crumble jump may also be required.

Dev note: FIXME: A variant of this strat could go to the item node instead of the door, possibly with slightly different heat frames at the end. FIXME: As an alternative to doing a Crystal Flash, Golden Torizo could be used as a farm, with canRiskPermanentLossOfAccess.

This is possible by jumping on the crumble blocks into a mid-air spring ball jump, or by avoiding them. The crumbles can be avoided by starting with either an air ball, a 3 tile high mid-air morph, or a low spring wall. These are generally safer, as bouncing on the crumble blocks with Spring Ball is trivial.

Avoiding the acid completely requires precise movement. With Spring Ball and Bombs, jump into IBJ to delay while waiting for the acid. With just Spring Ball, perform a well-timed pause to trigger immediately after Samus jumps to get enough horizontal momentum to cross the second Hibashi and land in the alcove. A quick pause with a second spring fling on the descent can help a bit. With just Bombs, this is possible with well-timed, first-try double IBJs.

Start with Springball disabled. Jump over the spikes and midair morph. SpringFling on the way down, SpringBall bounce through the spikes, then SpringFling again to reach the statue taking only one spike hit.

The second jump is harder than a normal mid-air springball jump. Use either a stationary lateral mid air morph, to gain enough horizontal momentum, or a SpringFling to reduce Samus' fall speed as soon as it begins to build up. Shooting towards Pirates will cause them to stop in place and not fire back.

With Speed Booster equipped, run into the room using at least about 2 tiles of runway (at least $0.C extra run speed). If needed, perform two spring flings by pausing and unequipping Spring Ball, then pausing again and re-equipping it before bouncing on the first Grapple platform. Afterward, perform additional spring flings as needed to make it across the room, taking care to avoid the Powamp.

Enter the room morphed, either in a mockball on the ground or descending from a controlled bounce, with about 1 tile worth of speed (at least $0.9 extra run speed). Use Spring Ball to jump or do a controlled bounce after the transition. While descending and before bouncing on the first Grapple platform, perform two spring flings by pausing and unequipping Spring Ball, then pausing again and re-equipping it. Afterward, perform additional spring flings as needed to make it across the room, taking care to avoid the Powamp. Note that Samus must be fully morphed when entering the room (not in the middle of a morphing animation), or the spring flings will not work, assuming Speed Booster is not equipped.

Use Spring Ball to jump or do a controlled bounce after the transition. Bounce on the first Grapple platform. Then perform a 'spring fling' by unequipping Spring Ball while descending, to reset Samus' vertical speed and be able to make it across room.

Stay out of the water, and by extension the sand, of the room by using the spikes as platforms. Morphing before landing on the spikes helps to be able to control the knockback. The final spike jump (which would be the most difficult) is avoided by doing a crouch jump into spring ball jump into IBJ to reach the left door. Perform the spring ball jump near max height. Place the first bomb between about 4 and 6 frames after the spring ball jump; ideally it should be just above the water line. Press pause between about 5 and 10 frames after placing the bomb, to disable Spring Ball (a 'spring fling', to reset fall speed). Place the second bomb soon after regaining control, while the game is fading back in. A spike hit in the center of the room can avoided by doing another spring ball jump into IBJ (also with a spring fling).

Dev note: The IBJ at the left side of the room can be done without a 'spring fling' but is far more precise: the first bomb must be placed exactly two frames before the spring ball jump, and the spring ball jump should be performed just before max height, during the 4-frame window between 2 and 5 frames before the last possible frame to jump (there are also 1-frame windows at 0 and 8 frames before the last frame).

Dev note: This assumes extra run speed of $1.B entering the room, at least $2.6 when jumping (a 2-frame window in the worst case).

Roll off the above ledge and use both the vertical speed resets from first (un)equipping SpringBall and then by unmorphing in order to reach the door. Pause shortly after rolling off the ledge, after falling for 1 tile. The timing is very precise. A downback helps by shrinking Samus' hitbox.

Wait the water tide to reach its peak, then crouch jump into a spring ball jump into an IBJ. Perform the spring ball jump near max height. Place the first bomb between about 4 and 6 frames after the spring ball jump; ideally it should be just above the water line. Press pause between about 5 and 10 frames after placing the bomb, to disable Spring Ball (a 'spring fling', to reset fall speed).

Enter with at least 1 tile of run speed from an air room, with Speedbooster unequipped. Jump from near the end of the runway (though a jump from 1-2 tiles away from the end can still work). Press pause while crossing the narrow first sandfall, then perform a lateral mid-air morph after exiting the sandfall. Equip both Spring Ball and Speed Booster, and perform a mid-air Spring Ball jump at somewhere close to the maximum height. Unequip Spring Ball while descending through the wide second sidefall.
