Collect the Beetom and freeze it above and left of the Power Bomb Blocks in a way that Samus will be able to Moondance. Moondance until Samus falls through two tiles, wait for the Beetom to thaw and attach to Samus, then Moonfall again to sink through the solid blocks and reach the door with the Beetom. Use the Beetom to perform another extended moondance to leave with stored fall speed.
