When the Cacatac on the ground fires a spike, perform a Spring Ball jump to break the waterline and then hit the spike for extra height.

Requires:

{
  "notable": "Spring Ball Spike Boost"
}
"h_underwaterCrouchJump"
"HiJump"
"canSuitlessMaridia"
"canTrickyJump"
"canTrickySpringBallJump"
{
  "or": [
    "canInsaneJump",
    "canStationaryLateralMidAirMorph"
  ]
}
"canNeutralDamageBoost"
{
  "enemyDamage": {
    "enemy": "Cacatac",
    "type": "spike",
    "hits": 2
  }
}

Dev note: The crouch jump is not strictly necessary but it helps significantly.
