Shoot the block while moving up after a Space Jump; then speedball through the morph tunnel.

Entrance condition:

{
  "comeInBlueSpinning": {

Requires:

}
"canPreciseSpaceJump"
"canSpeedball"

Dev note: This can also work at much higher speeds but would be more difficult.

Run through the door and jump into a speedball to break the bomb blocks, timing a precise shot during the jump to clear the shot block. Note: Spazer can trivially break the shot block by shooting forward before jumping.

Jump through the door and into a speedball to break the bomb blocks, timing a shot during the jump, immediately after the transition, to clear the shot block.

If Spazer or Wave are available, the timing for the shot is more lenient; otherwise, jumping with lower extra run speed (between $3.2 and $3.F) can help widen the timing window. If using a lower run speed, it often helps to aim down before bonking the ceiling, to avoid falling short of the ledge.

Dev note: The run speed required is not overly precise, but certain ranges of speeds must be avoided (especially extra run speeds $4.0 and $4.1) to prevent Samus from getting too high of a jump and not being able to reach the ledge.
