There is just enough distance for a MidAir SpringBall jump to reach without HiJump, with either a crouch jump or air ball. To do this, pause and morph early in order to get a spring fling from equipping Spring Ball.

Requires:

"Gravity"
"canSpringBallJumpMidAir"
{
  "or": [
    "HiJump",
    {
      "and": [
        "h_maxHeightSpringBallJump",
        "canSpringFling"
      ]
    },
    {
      "and": [
        "canTrickyJump",
        "canLateralMidAirMorph",
        "canTrickySpringBallJump",
        "canSpringFling",
        "h_complexToCarryFlashSuit"
      ]
    }
  ]
}

Dev note: The h_maxHeightSpringBallJump is not a h_underwaterMaxHeightSpringBallJump, because Gravity is required.
