Diagonal shinespark up the climb to break the bomb blocks to the morph tunnels on the right. A frozen Pirate can be used to stop the spark just above the bottom tunnel.

Requires:

{
  "notable": "Behemoth Shinespark"
}
"Morph"
{
  "canShineCharge": {
    "usedTiles": 28,
    "openEnd": 0
  }
}
{
  "or": [
    {
      "shinespark": {
        "frames": 147,
        "excessFrames": 124
      }
    },
    {
      "and": [
        "h_ZebesIsAwake",
        "canTrickyUseFrozenEnemies",
        {
          "shinespark": {
            "frames": 24,
            "excessFrames": 1
          }
        }
      ]
    }
  ]
}
{
  "obstaclesCleared": [
    "A"
  ]
}
{
  "or": [
    "h_ClimbWithoutLava",
    {
      "obstaclesNotCleared": [
        "B"
      ]
    }
  ]
}

Dev note: FIXME: if Zebes is awake, it is possible to farm the Pirates in the room after breaking the blocks; this also applies to the other forms of Behemoth spark in this room (as long as the lava is not active).
