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 Zeb low in the pipe. Crouch and shoot works for that, or shooting as Samus is approaching it. Jump on the left side of the pipe and walk right until you get blocked by the frozen Zeb. Start the ice SBA facing right. The bottom particle will instantly kill the Zeb. Turn around towards the left. At the right moment, jump to prevent the tail particle of the clockwise rotation to freeze the Zeb inside the pipe. As Samus starts falling down again, push left to freeze the rising Zeb with the leading particle of the rotation. While preserving the remaining 2 particles, spinjump over the frozen Zeb to quickly get to the floor above Samus. Run left until Samus hits the wall. While in the standing pose and holding jump, press right to do a buffered turnaround spinjump. Holding L+R during the jump can help to stop at the correct position after landing. Wait until one of the remaining particles flies off and freezes the Zeb at the correct height. Move towards the right side of the floor below the Zeb pipe. While running left, un- and then re-equip ice to synchronize with the Zeb. At the left side, jump up and shoot up to freeze the Zeb one last time, then walljump up and do the clip. Note: If the Zeb drops something, the frozen position at the end will be 1 pixel lower. This doesn't matter, both pixels work.
