It is important avoid touching the invisible fireballs the Alcoons place. It is possible to bomb from the edge of the top door runway into the hidden morph tunnel, but if Samus is not at the edge, she will bonk and fall. After entering the morph tunnel, roll through the two camera scroll blocks a few times to overload PLMs. They are at the entrance and two tiles in the tunnel. Exit G-mode and go through the room to the far right door.

Entrance condition:

  "comeInWithGMode": {
    "mode": "any",
    "morphed": true
  }
}
