To minimize damage from the Hoppers, get stuck in the door relatively high and move quickly. Climb up somewhat less than 1 screen, until Samus' head appears between 1 and 3 tiles below the door. Then perform a turn-around spin jump to the right to get on top of the Grapple block.

Entrance condition:

{
  "comeInWithDoorStuckSetup": {}
}

Requires:

{
  "notable": "Hopper X-Ray Climb"
}
"canXRayClimb"
{
  "enemyDamage": {
    "enemy": "Sidehopper",
    "type": "contact",
    "hits": 2
  }
}

Dev note: It is possible to avoid all Hopper damage, but it is not clear if this can be done reliably. Two hits from the big Sidehopper appears to be a worst-case scenario.
