It is tricky but possible to cross the room without any damage by jumping over the Small Dessgeega on room entry then using a Power Bomb to kill several enemies. Note that crossing the room damageless is easier in indirect G-Mode. After crossing the room, use a Power Bomb then quickly exit G-Mode before it explodes in order to break the bomb and Power Bomb blocks above. Without Spring Ball, it is still possible to place the Power Bomb high enough to break all the blocks above from an IBJ and still exit G-Mode before it explodes.
