Place two Power Bombs, precisely on the fourth tile in the morph tunnel to overload PLMs. Samus should be barely visible in the tunnel, if not, use the right edge of the screen to track her moved distance.

Entrance condition:

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

Requires:

"canPowerBombItemOverloadPLMs"
{
  "itemNotCollectedAtNode": 3
}
"h_artificialMorphPowerBomb"
"h_artificialMorphPowerBomb"
{
  "or": [
    "h_artificialMorphSpringBall",
    {
      "ammo": {
        "type": "PowerBomb",
        "count": 4
      }
    },
    {
      "and": [
        "Morph",
        {
          "or": [
            "can4HighMidAirMorph",
            {
              "ammo": {
                "type": "PowerBomb",
                "count": 2
              }
            }
          ]
        }
      ]
    }
  ]
}

Dev note: Because of the gates, it costs 2 Power Bombs to get into the tunnel and 2 to get out the other side. There is no canRiskPermanentLossOfAccess, because there is no reason to go here except to get the item and leave. This is only useful if Samus has Morph, or the item is Morph.
