Damage a Covern to prepare it to be frozen. Stand a few tiles away from the bomb block, and walk toward it as the Covern is about to reappear. If successful, the Covern will spawn inside the wall but close enough that Samus can clip into it. Freeze the Covern by pressing against the wall, then jumping and shooting down. Run into the wall with as much speed as possible to clip into it. Once Samus is clipped into the wall, perform a low turnaround spin jump to the right and immediately turn back to the left while still spinning, using Screw Attack to break the bomb block. If Phantoon is already dead, a moonfall with two frozen Atomics can instead be used to clip into the floor to be able to break the bomb block.
