There is just enough distance for a MidAir Spring Ball 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.
