The most common method to reach the upper right door of the room is to charge a shinespark along the floor of the room, then do a diagonal spark while standing between the second and third floating islands.
If hp needs to be conserved for the Botwoon fight, you can farm the crabs in between charging the spark and activating it. You can also jump before activating the spark, lowering the distance, and hence the health, required.
Due to the slightly different physics used in the PAL version, this spark cannot be done from the floor, jumping up before activating the spark is required to clear the overhang.
