PLMs can be overloaded in direct G-Mode with a single Power Bomb if both items are still there and 2 PBs if only one item is. There is a row of tiles that works, just above and to the left of the right door. The row is one tile higher than the horizontal pipe that is part of the door frame, spanning from the left to one tile away from the right wall.

Entrance condition:

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

Requires:

{
  "notable": "G-Mode Overload PLMs - Power Bomb the Items"
}
"canRiskPermanentLossOfAccess"
{
  "or": [
    {
      "itemNotCollectedAtNode": 7
    },
    {
      "itemNotCollectedAtNode": 8
    }
  ]
}
"h_artificialMorphSpringBall"
"h_artificialMorphPowerBomb"
"h_artificialMorphPowerBomb"

Dev note: This canRiskPermanentLossOfAccess variant is only added from this door, as the only other place to use overloaded PLMs would be the top left bomb block, and if you can get here artificially morphed, you can get to the top left and instead use the bomb on the block.
