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).
