Samus can Crystal Flash to have enough Energy to take a crab hit or to get some Reserve Energy, but then she will not be able to use X-Ray to exit G-Mode, and will require a Reserve Trigger. The Crystal Flash needs to be done before unmorphing, while being careful not to kill the global crab. Samus then needs to jump into the speed-locked item and hit the crab to trigger Reserves and exit G-Mode. This can be done with HiJump, Gravity, Spring Ball, or Ice. Turn around while inside the item to collect it.
