There are scroll PLMs one tile to the left of the bomb blocks which can be used to overload PLMs. The bomb blocks then become air and can be passed through. Use Bombs, SpringBall, or a Geemer damage boost to get across the gap without unmorphing. To survive a Geemer hit, you will need Varia or Gravity or to come in with more than 4 energy (e.g. by coming in with indirect G-mode after leaving with G-mode immobile).

Enter the room while building a shinespark and use it on the lowest part of the ramp to cross the room and reach a raised ledge on the right side wall. From there, use SpaceJump to escape the water. Carry the shinespark to the bottom of the ramp by delaying the first Choot with two Power Beam shots, killing it, or bounceballing through it. The Choot can be shot diagonally from the middle platform, and again by running off that platform and aiming down to float above it.

Enter the room while building a shinespark and use it on the lowest part of the ramp to diagonally spark up and out of the water. Unmorphing with the correct timing and positioning for the Shinespark are very precise, and there are no extra frames on the Shinespark timer to work with. Carry the shinespark to the bottom of the ramp either with a bounce ball which takes damage from the Choot, or delay the first Choot with two shots and then use a late mockball. Then shinespark up and use SpaceJump to reach the door.

Have Samus shoot the shot block revealing the item and then quickly get hit by an enemy at the peak of her jump in order to reach the item. No directional inputs should be held while getting hit by the enemy in order to have a neutral boost and reach the item. This is traditionally done with the swooping Reo; after a few failed tries, it may help to reset the room to reposition it. The global Geemer may be easier to use, although it takes longer to get there; jump as it starts moving horizontally again while it is 3 tiles away from the item.

    "enemy": "Geemer (blue)",
    "type": "contact",

Dev note: Although the Reo is traditionally used for the boost, the Geemer does less damage and should still put this in logic with low energy.

Freeze a Zebbo inside the wall above the right side of the spikeway, close to the ceiling thorns. Face right, equip X-Ray, move at least a few pixels away from the wall, and jump straight up into the ceiling thorns. If successful, Samus will be knocked back into the wall and end up standing inside it. Use X-Ray immediately to prevent additional thorn hits. If Samus is high enough to be touching the thorns, then i-frames will continue to be refreshed once per second. While X-Ray climbing, be careful to only release X-Ray soon after i-frames are refreshed. Crouch before pressing X-Ray again.

"canWallIceClip"
{
  "thornHits": 1
}
"canXRayClimb"
"canUseIFrames"
"canNeutralDamageBoost"

Dev note: Standing at least 3 pixels away from the wall ensures that knockback pushes Samus fully up against the ceiling; there is also no problem with standing further right, even hanging off the ledge: as long as Samus is still in range to take damage from the thorns above, they will be able to knock Samus into the wall. It is possible to freeze the Zeebo lower, but if Samus is too low, it will be necessary to take 3 thorn hits. It is also possible to get stuck inside the wall by taking knockback from a floor thorn, or by using a frozen Beetom as a platform. However those methods are not any easier, more damage will be taken, and the climb will be longer. If Samus begins climbing at a level below the ceiling thorns, then as Samus approaches the thorns, X-Ray will need to only be released while turning to the right, in order to prevent the thorn hits from knocking Samus out of the wall.

Freeze a Zeb inside the left wall of the room, and use it to clip into the wall and X-Ray climb. Note that jumping directly against the wall to clip into it will put Samus into a forced crouch, unable to use X-Ray. Samus may either 1) perform a Crystal Flash to stand up, 2) use neutral knockback from a Reo to put Samus standing inside the wall, or 3) use the frozen Reo as a platform to run and clip into the wall. To manipulate the Reo into a suitable position, lure it to the left and crouch at the edge of the platform; jump as needed to bring it back on camera when it goes off; it should perform 4 big swoops down to the left, 2 small swoops (hitting the overhang above), then 5 more big swoops, after which it will enter a slow hover moving directly towards Samus. Freeze the Reo when its left side is approximately flush with the ledge, or up to about a tile to the right. After X-Ray climbing about 1.5 screens, the sound of the crumble blocks breaking is an indication that it is safe to end the climb, either by jumping up or by falling out to the right. Alternatively, there's no harm in continuing to climb, as the lack of door means it's impossible to climb beyond the destination.

Dev note: The Zeb moves 2 pixels per frame, and there are 3 positions where it can be frozen inside the wall using Ice beam alone, namely 2 pixels, 4 pixels, or 6 pixels deep inside the wall. For the method that uses the frozen Reo as a platform, only the 2-pixel-deep position will work; by moonwalking back inside the 2-tile space, it will work 100% reliably as long as the Zeb is frozen in that exact spot. For the method that jumps directly into the wall (with a Crystal Flash), either 2 or 4 pixels can work, or 6 with SpeedBooster; it will work more reliably the less deeply the Zeb is frozen inside the wall. Likewise, with the Reo knockback method either 2 or 4 pixels can work, though it is more reliable in the 2-pixel position; it helps to take the knockback a few pixels away from the wall, as it takes a few frames for the horizontal speed of the knockback to reach its maximum. The trick can work with Samus facing either toward or away from the wall when taking knockback; facing away makes it easier to quickly kill the Reo afterward to avoid taking a second hit.

Freeze the Reo when its left side is approximately flush with the ledge, or up to about a tile to the right. After X-Ray climbing a little over half a screen, it is possible to aim up and shoot the door (if it is blue) and listen for if it opens, to test if you are high enough to safely jump up. Alternatively, the sound of the crumble blocks breaking will indicate when Samus' feet are level with the bottom of the door.

Traverse the room while rolling on the thorns and avoiding the Samus Eaters. Roll from the first platform onto the thorns under the first set of Boyons. When just past the first Boyons, turn right and wait on the safe spot for a second to overload PLMs. Move right to touch the thorns and use that to damage boost leftwards onto the next thorns and roll into the third Samus Eater. Place a Power Bomb and then quickly unmorph and jump onto the block above and exit G-Mode before the Power Bomb explodes to break the wall. Note that if Samus is teleported into the Samus Eater when exiting G-Mode, then PLMs weren't properly overloaded before entering it. PLMs can be overloaded by waiting on their petals before entering them. Also note that there are much easier strats with more Energy or more Power Bombs.

Traverse the room while rolling on the thorns and avoiding the Samus Eaters. Roll from the first platform onto the thorns under the first set of Boyons. When just past the first Boyons, turn right to damage boost up and hit the block and fall back on the thorns. While still facing right wait for the thorns to hit again; use the boost to get onto the next set of thorns and roll across them into the third Samus Eater before using a Power Bomb. Use the Power Bomb to boost up into the thorns. Hit the thorns again to get next to the Chozo statue. Place another Power Bomb and exit G-Mode before it goes off to break the wall. Note that if Samus is teleported into the Samus Eater when exiting G-Mode, then PLMs weren't properly overloaded before entering it. PLMs can be overloaded by waiting on their petals before entering them. Taking 2 thorn hits while under the first Boyons is important for this reason.

Either race the nearby Sova to the morph tunnel or wait for it to come back through the morph tunnel and use a Super to knock it off behind Samus. Alternatively, it is possible to wait for the global Sova to come around. Build speed on the lower platform and jump towards the morph tunnel while performing a Midair Morph to reach the Sova in time. Guiding the local Sova around through the shot block again can be faster, but is not expected.

}

Dev note: The global Sova is moving while the player reaches this node and this heatFrame count reflects that.

Use a very well timed and precise walljump into morph to hit the global Sova so that the damage bonks Samus up to the door ledge. Aim for the lowest part of slope looking wall tile, where it does not look possible to make contact with a walljump, and fully delay the jump. To try again, the Sova loops to the left side wall. Or a Super can knock it off the wall to climb the right side again.

Wait for the global Sova to begin climbing the wall below the door. Time a walljump into instant morph where Samus boosts off of the Sova with the right timing to bounce up to the door's ledge. The jump must be a fully delayed walljump. Normalizing the camera can help with timing the walljump. The damage boost can be attempted again when the Sova climbs down the left wall, or by knocking it off the wall with a Super Missile.

Dev note: A damage boost allows getting up without a crouch jump, e.g. to preserve a flash suit.

Ride the Geruta left to reach the missile location by freezing it repeatedly. Stay on its left side when it touches the ceiling for the enemy to continue moving forward. It may not be possible to climb back up to the Geruta if Samus falls. When it moves towards the ceiling, reset Samus' fall speed using an unmorph or by taking knockback damage, in order to wait for the Geruta to fall low enough to refreeze.

Clears obstacles: A, B, C

Dev note: This is only notable with wall jumps disabled. FIXME: Consider also adding a Mella version of this strat. It takes longer to setup but allows retrying. The Mella version does slightly less damage. With either the Mella or Sova, you could kill it and collect its drop after getting onto the ledge; for the Sova you'd have to wait for it to come back around.

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).

Stay out of the water, and by extension the sand, of the room by using the spikes as platforms. Landing on spikes aiming down with no other direction pressed can help control the knockback. Requires knowing the position of every spike in the room. The final spike jump is very difficult.

Freeze one of the Menus (bugs) in a position where you can use it to get into the morph passage. One of the easier methods is with a damage boost. Stand in the water, take a hit for positioning, and freeze the bug near but left of Samus. Then morph on top and damage boost into the morph tunnel as it unfreezes.

Use the projectile from a fully submerged Evir to boost Samus into the sandfall, providing just enough height to make the first and hardest jump. Time the projectile to hit Samus when at the maximum height from a jump. The hit must be on the right side of Samus and with no inputs held, but also hold forward during the damage knockback to move through the sandfall. Getting a good jump while on the right side of the next floating block can get Samus to the leftmost block. With a clean jump off of the sand, Samus can then get onto the final vertical pillar.
