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. Two Beetom hits are assumed, but with failed attempts it could take more, possibly requiring leaving the Beetom and going back to the right to farm.

Gain a shinecharge by running right-to-left, either using the short runway (with unbroken Super block) or an extended runway by taking a spike hit. Then spin jump, hit the ceiling, aim down, break the Super block, and turn around to quick drop through the crumble block. During the item message box, buffer the inputs to turn around to the right and jump. Once under the crumble block (the left part of it), press up while still holding jump, to immediately activate the spark and make it up in time.

Perform a quick-drop through the Crumble block, and grab the item. During the item message box, buffer the inputs to turn around to the right and jump. Break spin just before you would hit the respawning crumble block, in order to clip up through it. Then perform a crumble jump to make it out.

This is possible by jumping on the crumble blocks into a mid-air spring ball jump, or by avoiding them. The crumbles can be avoided by starting with either an air ball, a 3 tile high mid-air morph, or a low spring wall. These are generally safer, as bouncing on the crumble blocks with Spring Ball is trivial.

  "obstaclesCleared": [
    "A"

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.
