Perform a speedball into a temporary blue chain to reach the door. If HiJump and Spring Ball are unavailable, then getting out of the water requires a very precise jump: delay aiming down for the mid-air morph until after Samus is above the water line.

Requires:

{
  "getBlueSpeed": {
    "usedTiles": 32,
    "openEnd": 1

    "canInsaneJump",
    "HiJump",
    "canSpringBallBounce"
  ]

Exit condition:
