Get a Zeb to move left into the morph passage, and reach the end of the tunnel before it. Freeze the bug at the correct height, such that it will move and be able to hit Samus while in the morph tunnel. While in the first two-tile tall region, shoot and refreeze the bug. Then go to the second two-tile region and shoot the block. Return and lure the bug such that it hits Samus and boosts her up and onto the ledge to escape. Be careful not to despawn the enemy by moving it off camera, except while it is frozen. This strat is a one-shot try and failure is a softlock.
