This is a long temporary blue chain with X-Ray turnarounds to climb up and destroy the bomb blocks blocking the top morph tunnel. Breaking the bomb blocks is difficult because there is not enough space above them to get a neutral bounce. It is best to break them by jumping from the top platform (inside the 3-tile-high space), as this provides a 2-frame window for the morph; in comparison, jumping from the platform below requires a frame-perfect morph. If Spring Ball is available, it can be used to increase the window by one frame.

Use R-Mode to get a blue suit to cross the room and get the item, or to leave the right shinecharged. In R-Mode, fill your Reserves at the farm. Damage down again so that Samus is within 1 Zebbo hit from triggering Reserves. Gain a shinecharge in-room without gaining more energy. It is possible to time the despawn of a drop with the acid if no ammo is owned. Shinespark vertically, such that a Zebbo can hit Samus in the wind-up to cause a reserve trigger, giving a blue suit. It is then fine to farm the Zebbos again.

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 the bomb block at the bottom right of the main shaft. Bring a Zeela down to the bottom of the room. Morph inside the tunnel, take a Zeela hit, then jump, aim down, and shoot to freeze the Zeela as it starts to move up and while Samus is close to landing. Jump and aim down to get on top of the Zeela. If the Zeela is precisely positioned exactly 12 pixels above the ground, you can press up to make Samus stand; Otherwise, if you have X-ray, then the Zeela should be frozen lower, and you can morph and unmorph and use X-ray to force Samus to stand up; in this case there is a 6-pixel window over which it works, with the Zeela being between 4 and 9 pixels above the ground. In either case, after standing up on top of the Zeela, jump and aim down to break the crumble block. Then, before the crumble respawns, morph and use Spring Ball (if available) to jump back up and into the tunnel; without Spring Ball, a quick mid-air morph also works but is more difficult.

Go into the morph tunnel below the Charge Beam location and Crystal Flash to force a standup and jump through. Samus is now unable to use X-Ray. Without Morph, be careful not to overload PLMs using the camera scroll blocks on the path upward. Then partially floor clip into the left side of the bomb block, and jump to clip through and escape. To exit G-Mode, damage down until the reserves trigger, which can be done most quickly using the Sidehoppers.

Using Speed Booster, run through and break the bomb wall to free the global Zeela. Break the speed blocks just before the Zeela gets to them in order for it to go down to the bottom half of the room. The speed blocks respawn very quickly, so this requires very precise timing. Normally, it takes the Zeela a minimum of 2 minutes to setup, but a super can make it fall down the shaft, saving 30 seconds. It may be easiest to knock the Zeela from the ceiling directly into the hole, saving another 30 seconds: Shoot a well-timed Super diagonally at the ground just before breaking the speed blocks.

Very quickly cross the room, collecting both items without falling into the lava. A Power Bomb in the middle of the room sets up the Sova drops and adds lag which makes the block item easier to collect with a Flatley jump. Farming the left sova and middle dragon increases the chances of getting enough health drops, but it may still not be possible with poor drop luck. Pause abuse can be useful for reaching the right side drops if the left side's luck was bad.

Either jump over a Cacatac or tank a spike hit. Perform a mid-air spark through the speed blocks. Then run to the right and back to get speed to go through the rest. If performing the spark with low energy, there is a risk of ending the spark above the spikes or in front of the Pirate; to be safe, assuming Samus has heat protection, begin the shinespark with between 73 and 88 energy, or at least 106 energy; with a buffered crumble jump to the right, up to 94 energy can work.

Release the ceiling Sova while being careful not to kill it if using Power Bombs. The Sova takes 90 seconds to get to the door if the Power Bomb blocks are broken and 45 seconds if they are not. Using a Super when the Sova is exiting the ceiling takes only 12 seconds.

Lure a Mella from the right by breaking the speed blocks or using Morph. Then manipulate it to go high enough to be used in the left doorway. Raise the Mella up to just below the door's ledge then climb up to the door. Then the Mella will start moving upward, which means it comes at you partially blind. Getting it to reach the door, and not just short of the door is the hardest part. If it drops below the camera it will be necessary to go back down and raise it some more.

This strat requires much farming. It assumes a capacity of and starting with only 5 supers for five sessions of farming. A safe farming method is to face left while standing in the safe spot. Then fire straight up to shoot the orbs as they appear. Jump up while GT's beak is not open to collect the drops. Plasma allows all of the orbs to be broken at once. Grapple allows for more drops to be collected by shooting diagonally, and collecting the items using Grapple. Keep the number of current Missiles below 31 so that GT will be guaranteed to use the attack which creates drops. Firing Supers requires a very steady fire rate so that for every Super Missile caught by GT, the next 4 Supers do damage.

On room entry, place a Power Bomb to kill the Atomic and land on the Workrobot. Wait for the Workrobot to move across the room until it meets with a second robot. Depending on where the robots meet, either roll off and quickly roll under the Atomic, stay on for a second to try to lure the Atomic left a bit, or use a Power Bomb to kill it. Be careful not to hit any of the invisible, stationary lasers, and don't place any Power Bombs too close to the right wall or it will hit the bomb block and it will no longer be passable. Quickly use the camera scroll blocks just left of the bomb blocks, in order to overload PLMs and go through them before the Atomic hits Samus.

Bounce the snails around the room in order to destroy the sand blocks, opening up the runway. Without Gravity, this requires greater caution as the water will slow Samus down and increase the risk of taking damage from a snail. A snail can be made to bounce in 3 ways: shooting it off a wall or ceiling, kicking it on the ground, or touching it while it is already bouncing. Kicking a snail involves running or jumping into it with a non-zero amount of run speed, gained by dashing for at least one frame while in air physics. A snail can be kicked from any direction when in its initial (not angered) state or when it is stunned for a moment after being shot. While a snail is angered and is moving quickly, it can only safely be kicked from a certain side: from behind if on the ground, or head-on if on the ceiling (and not at all while on a wall). If Morph is unavailable, be careful not to let the snails go off-camera, and avoid getting stuck in two-tile-high spaces. If a snail is on the ground and still on camera, it can be forced to move toward Samus again by shooting it; let it wrap around the right side of the room onto the ceiling, where it can be shot to cause it to fall and continue destroying sand blocks.
