If Spring Ball is unavailable, then either crouch jump and morph from the stairs, or run and jump into morph from the right of the stairs. If you have HiJump, it must be disabled.

Requires:

"Morph"

  "obstaclesCleared": [

}
{
  "or": [
    {
      "and": [
        "canCarefulJump",
        "canDisableEquipment"
      ]
    },
