Entrance condition:

"comeInWithGrappleTeleport": {

}

Requires:

{"or": [
  "canUseFrozenEnemies",
  "HiJump",
  "canSpringBallJumpMidAir"

Dev note: The requirements are for getting onto the platform. FIXME: it would probably be better to add another node below the platform; and flash suit is also an option for getting up onto it.
