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"

        "h_useMorphBombs",

    },
