Use normalized movement to land on the sand without losing a blue suit. One way is to do the following: from the high platform at the right of the room, jump up to bonk the ceiling before falling into the sand; jump up to lure a Mochtroid down, and destroy it with the blue suit; if HiJump is unavailable, perform the first IBJ all the way left against the Grapple block wall to prevent the higher Mochtroid from coming on camera; from the platforms at the height of the top door, simply walk off the ledge; from the platforms two tiles above the sand, do a full height jump; from the sand itself, do full height spin jumps, ideally without breaking spin.

The same approach to the normalized movement generally works with or without HiJump: but if performing many jumps in a row from sand to sand with HiJump, it is recommended to alternate between breaking spin and not breaking spin, to keep Samus' vertical subpixels in a good range. In any case, if failing an IBJ, unmorph before landing on the sand, in order to have a chance to keep the blue suit.
