Wait for a global Geemer to make the long trip along the map, or shoot a Super 20 to 30 seconds after entering the room to knock it off the ceiling and save a lot of time. Freeze it just after it starts climbing the bomb blocks. Spin-jump above it, which will put Samus into a forced crouch where X-Ray cannot be used. Use Grapple to kill a second Geemer, restoring the ability to use X-Ray. Use X-Ray to stand up, then jump up through the ceiling.

Wait for a global Geemer to make the long trip along the map, or shoot a Super 20 to 30 seconds after entering the room to knock it off the ceiling and save a lot of time. Hold right against the bomb blocks, take damage from the Geemer, jump, aim-down, and shoot the Geemer shortly before landing. Samus should end up standing on the ground with the Geemer frozen on the wall with a 4-8 pixel gap between it and the ground (overlapping Samus' hitbox). Facing the bomb blocks and pressed against them, jump while holding down (but not crouched) and then hold forward (or forward and down) 5 frames later to break the aim-down pose. If successful, Samus will clip up through the ceiling. This can be attempted several times before the Geemer thaws.

Shoot a Super as a Sciser crawls near the top door, then freeze it mid-air and use it to clip up past the door shell. If you don't have Morph and X-Ray, you must shoot the Super while the Sciser is on the slope near the door, not on the door itself.

Freeze a bug three tiles to the right of the morph tunnel entrance, directly under the tile where ceiling is higher. Jump onto the bug, crouch, and jump up. The bug must be at a very precise pixel height unless using XRay and Morph. Note that although the ceiling here is 3 tiles thick, only the bottom tile is solid; the other two are slopes pushing Samus up, allowing the trick to be done.

Jump and freeze the Beetom at a precise location in order to jump through the crumble blocks. The pixel window is larger and higher with Morph and an X-Ray Stand Up.

Lure the Reo (Bee) to the left to use it as a platform for ice clipping up through the crumbles to the Power Bomb room exit door. Watch the Reo bounce against the left wall until it does a slow hover towards Samus. There is a very small timing of when its right claw is above the small pale spore next to the big red spore, when Samus should jump to be above the Reo. Crouching with Samus' front toe beneath this spore (facing left) will cause the bee to fly with the correct timing after Samus takes knockback damage, with a 3 pixel window. This will cause it to fly left and into the two tile gap below the crumble blocks. Freeze it once to get above it, and then again for the ice clip. Once it is up there, the bee will become stuck and the room will need to be reset. But if the Reo does not fit in the hole, it is possible to just wait near the ledge for another slow hover to try again. With this strat, there is at most a two-frame window in which the Reo can be frozen. One frame (setup dependent) may let Samus crouch jump through the block; the next frame Samus can use Morph and X-Ray to clip through.

But if the Reo does not fit in the hole, it is possible to just wait near the ledge for another slow hover to try again. With this setup, there is a one-frame window in which the Reo can be frozen. Without a precise setup, there is typically no way to clip through without Morph and X-Ray.

Raise a Zeb to be just below the crumble blocks and blindly freeze it to set up an ice clip to reach the Power Bomb room exit door. Get a bug from the pipe to spawn facing left and freeze it while moving to the ledge below the Hopper room door. While crouched, a spazer or wave beam shot will shoot through the floor in front of Samus. The bug must be frozen at a height between where Samus is crouched and where she is standing. Once frozen, somehow track how long until the freeze effect expires, and when the bug will reach the crumble blocks. If the bug is off camera when not frozen, it will despawn. Refreeze the Zeb below the crumble blocks and ice clip up to reach the door.

Freeze the Mella at a precise location in order to jump through the crumble block, then wall jump up the long channel and mid air morph to get out. The Mella pixel positioning window is larger and higher with Morph and an X-Ray Stand Up. One normalization which requires moonwalk: Kill all but the middle Mella without letting the middle one move from its starting location by keeping it frozen if Samus passes through. From the right, moonwalk backwards one pixel at a time until the Mella is no longer on screen. Shoot ice towards it, then move it on screen so that it is frozen immediately. Move to the left and press against (but don't roll under) the speed blocks before the Mella thaws. Moonwalk backwards 5 pixels, then in very quick succession, press right and then jump to do a buffered spin jump. The Mella should move horizontally and can then be used to clip through the crumble block.

Ice Clip through the crumble blocks using a Multiviola from the bottom of the room and then Crumble Jump to clip through the bomb blocks. The ice clip can be setup by standing in a corner and firing forward when the Multiviola hits Samus, if it is moving downwards towards Samus. The Crumble Jump is done by aiming down (not immediately) after jumping, then changing Samus' hitbox once above the crumble blocks, and jumping again.

The pixel window is larger and higher with Morph and an X-Ray stand-up, in which case a standing jump is used. If Phantoon is not defeated, stand on the stairs so that Samus is just a few pixels lower, then freeze the Covern low in its cycle. Alternatively, freeze it high then perform a tight down grab to get onto it for a pixel perfect clip.

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.
