Swing counter-clockwise around the left-most Ripper closely (pressing up to retract Grapple), positioned as far left as possible while avoiding getting caught on the stalactite. After swinging under the stalactite with high enough speed, hold down to extend Grapple to push Samus to the left slightly, then release Grapple while Samus is still nearly horizontal. Quickly morph and frame-perfectly pause to equip or unequip Spring Ball. If successful, Samus will continue gaining fall speed while on the ground morphed. Immediately roll left through the door, which should have been opened in advance.

Dev note: It is possible to do this with a flash suit, and no crouch jump, but it requires a frame perfect jump and then a Spring Ball jump within 3 pixels of its peak.

Set up to Damage boost off the highest Fireflea at the apex of Samus' jump, right next to the statue's claw. The positioning of the Fireflea is very precise, and this can only be attempted once. To position the Fireflea, jump to move it on camera and move it off camera while it is at the top of its circle. Be careful not to touch the Fireflea while setting up its precise positioning. Note that morphing can make the boost a little easier, and a crouch jump can also help, but is not required.

Freeze a crab at a very precise position in order to clip through the center Morph tunnel without a way to see. Use a frozen crab on the opposite wall in order to better time the crab being used for clipping and as a way to climb on top of it. Ice Beam on its own has a high chance of hitting a wall instead of the crab; straight vertical shots can help. Gravity has a 2 pixel clip window while Suitless there is only 1 pixel up higher which requires a precise down grab to get onto the crab.

Morph or unmorph while passing through the Skultera, to avoid taking knockback. Arm pump as needed, to move left a tile past the initial ledge, to avoid bonking a floating platform above. Grapple jump quickly to get past the second Skultera, or kago through it as well.

Using the slow global crab to ascend the top section of the room requires the speed blocks to not be broken. Jump with either Springball or HiJump onto the global crab while it is climbing the section above the Speed locked item. Have Reserves set to manual and return them to auto after taking a deadly crab hit in order to gain two damage boosts. If the Speed blocks are broken, the global crab will not be able to reach this part of the room. If Morph is unavailable, then a down-grab must be done blind: buffer the down input through the reserve refill, then press forward immediately after taking damage.

Crouch jump while holding shot to jump high enough to grapple horizontally to the second-lowest block. then fall, aim diagonally up, and grapple to the opposite wall after moving close enough to it, repeating this until Samus is above the water line. Grappling the same wall is also an option: in this case Samus will already be facing the wall when falling, so simply hold angle up and fire Grapple again immediately when Samus begins to fall; if done quickly, Samus will climb up to the next Grapple block.

From the bottom of the sand, shoot upwards to break the block then Shinespark up. To use a flash suit in deep sand: vertically - quickly roll the directional inputs from forward to up and jump. diagonally, with minimal horizontal speed - while holding angle, quickly tap forward then press and hold jump. Alternatively, to save Energy, shoot the block without falling into the sand, then reposition and spark up left. This can be done with a midair unmorph then shoot up, or from shooting up from the sand surface then quickly spin jumping off in order not to sink.

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 somewhat late, and by switching from holding left to holding right one frame later (a perfect 'boomerang').

Lower run speeds are generally better, as long as the extra run speed is at least $3.2. 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 last-frame spin jump, and make it to the platform below the top door. 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 somewhat late, and by switching from holding left to holding right one frame later (a perfect 'boomerang').

The optimal amount of extra run speed is between $3.2 and $3.5, by using 13 tiles of runway or about a half tile more or less; 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. Extra run speeds between $3.6 and $3.F can also work, but with shorter windows. 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.

Avoid the Baby Metroid with no items at all. Jump over it many times in order to clear a path through the seaweed. With a counter clockwise setup, stand as close to the transition as possible while allowing the Baby to circle Samus. Then jump towards the transition and touch it with a walljump check. A clockwise setup is more difficult to clear the seaweed, but can jump directly into the transition.

Dev note: FIXME: Add a Baby Skip with a flash suit. Note, however, it will only pair with rooms that have an entrance condition where Samus is sparking. In order to have it be properly implemented, all horizontal doors will need to have a shinespark entrance condition added.

Avoid the Baby Metroid by jumping over it many times in order to clear a path through the seaweed.

Requires:

{
  "notable": "Baby Skip Without Wave or Speed"
}
{
  "obstaclesNotCleared": [
    "A"
  ]
}
"canMidAirMorph"
"HiJump"
"canTrickyJump"

"h_trickyToCarryFlashSuit"

Jump over the Baby Metroid to avoid getting grabbed. Use Wave plus a Wide Beam to clear much of the seaweed with each shot. The classic counter clockwise skip ends with a mid air morph into the transition.

Requires:

{
  "obstaclesNotCleared": [
    "A"
  ]
}
"Wave"
{
  "or": [
    "Spazer",
    "Plasma"
  ]
}

"HiJump"

Dev note: A wide beam is used to avoid picking off stray seaweeds since that is a skill used in waveless skip.

Freeze the Pirates and use them as platforms to climb the room. Sometimes the Pirates may decide to climb the wrong way; patience may be required to wait for them to come back. If enough energy is available, it can be easier to use i-frames to jump up through a Pirate and freeze it from above, compared to jumping around it.

Requires:

"canBePatient"
"canTrickyUseFrozenEnemies"
"canTrickyDodgeEnemies"
{
  "or": [
    "Wave",
    "Spazer",
    {
      "ammo": {
        "type": "Missile",
        "count": 8
      }
    },
    "canBeVeryPatient"
  ]
}
{
  "or": [
    {
      "enemyDamage": {
        "enemy": "Tourian Space Pirate (all)",
        "type": "contact",
        "hits": 4
      }
    },

}

Dev note: Plasma is hard to use effectively as it's easy to accidentally kill the Pirates with it.
