Dev note: 1 extra tile is added so that you can jump into the door, simplifying the inputs a bit.

Either freeze the Geruta and turn off and on Ice to quickly thaw it and save Energy, or carefully jump over it without freezing it or getting hit. Then lure it left by jumping towards it from below. Freeze it when it performs a larger swoop and use it as a platform to get to the item.

Requires:

This can be a very long fight if Crocomire is stingy with the farming phases. Farming requires careful dodging in order to minimize energy drops. Delay grabbing all of the drops until necessary to reduce the chance of running out of ammo.

Sets flags: f_DefeatedCrocomire

Dev note: This strat is notable, not because it's harder than its required tech, but because its tedious, RNG heavy, and players might not want to encounter it. Crocomire does not have a farming phase until he has been hit twice. It is possible to get to the farming phase with 1 PB, but sometimes Croc will just rush Samus into the spikes without ever having farm phases, so it is ignored here.

Jump into the respawning shot block. It helps significantly to aim down to get trapped into the block. A normalized method to set this up is to shoot the block then immediately perform 5 full-height jumps.

        "canInsaneJump",
        "canComplexCarryFlashSuit"
      ]
    }
  ]
}

Dev note: The 900 heat frame option gives two leniency attempts. This is likely only useful to avoid a crouch jump and preserve a flash suit. This is not needed on strats that go directly from 9 to 2, because they require a crouch jump or X-ray.

Glitch through the Mother Brain Zebetites by using a frozen Rinka and i-frames. Freeze the Rinka at its spawn location, then spin jump or down-back onto it after acquiring i-frames to clip inside of the Zebetite, then jump through. I-frames can be acquired from a Rinka hit, a turret shot, or from the Zebetite itself. Note that Zebetites cause i-frames but deal no damage. If Screw Attack is equipped, then a down-back must be used, since spin jumping will cancel i-frames. With Ice+Wave, Samus can freeze the Rinka from above with an angle-down shot; Otherwise Samus must go below, press against the wall, and freeze it with an upward shot. With Ice+Plasma, Samus must be crouched when firing the shot.

Dev note: This technically requires f_KilledZebetites1 to not be set, but there is minimal risk of loss of access, because there is no reason to kill any Zebs without being able to kill them all. It is also possible to Ice Zeb skip through the second Zeb with a morph/unmorph/remorph on a frozen Rinka; this is known as a Remorph Zebetite Skip or a Spring Ball Zebetite Skip. Technically this strat involves `canWallIceClip` but we don't include that requirement, since the positioning of the Rinka is freely normalized, which makes the trick easier than this tech would normally imply. FIXME: It is possible to Ice Zeb Skip out, but it is much harder and would only be useful if getting here with canRiskPermanentLossOfAccess.

Dev note: This is not the level of precision that would call for canBlueSpaceJump.

Time Samus' movement carefully to roll underneath a Tourian Hopper and also race it to the far door. Enter the room morphed and let the hoppers jump against the wall a couple of times. After the lower hopper has long enough time between jumps, roll under and run to the door.

Spin jump into the room with Screw Attack, holding left through the transition to land near the door. Do a turn-around spin jump to the right, bonking the ceiling and overhang and then falling straight down. Then run and spin jump to the right through the Hoppers, to make it to the door without taking damage.

Use at least 4 tiles of runway to gain speed, running through the transition. Hold down during and after the transition in order to aim down and squeeze under the Hopper. Then immediately run to the right to make it to the door without taking damage.
