On entry, artificial morph and land on the doorsill without touching the crumble blocks below. Move to the edge of the ledge in order to be able to place bombs that will hit the Power Bomb blocks while avoiding falling. Use a Power Bomb, Wave, or a quick Plasma shot while falling to kill the Sidehoppers. With a blue suit it is also possible to kill the hoppers with Spring Ball. Hold jump and exit the tunnel and keep holding jump until both hoppers are killed. If Samus exits the tunnel and falls without jumping, she will take a hopper hit.

Entrance condition:

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

Requires:

"canComplexGMode"
"canArtificialMorph"
"h_artificialMorphIBJ"
{
  "or": [
    "h_artificialMorphPowerBomb",
    {
      "and": [
        "Morph",
        "Wave"
      ]
    },
    {
      "and": [
        "Morph",
        "Plasma"
      ]
    },
    {
      "and": [
        "h_useSpringBall",
        {
          "haveBlueSuit": {}
        }
      ]
    }
  ]
}

Dev note: It's possible to drop down past the Sidehoppers and Reos without killing them, but it's very difficult. FIXME: This could be done in indirect G-mode, but it would require entering unmorphed or with upward momentum to avoid touching the crumble block.
