Exit G-mode while on the item pedestal, while off-camera, then return to the right through the Dessgeegas that can't damage Samus off-screen. It is possible to use a Power Bomb and quickly exiting G-mode to have the bomb block broken on exit, but this will also partially break the Power Bomb blocks and could make exit traversal less straightforward.

Requires:

"h_heatedGMode"
"Morph"

      "and": [
        "h_useMorphBombs",

        }
      ]
    },

          "heatFrames": 850
        },
        {

Dev note: FIXME: The Hibashi doesn't need a 4th PB in the power bomb case.
