To get a crab at the top of the room, use a Super to knock off the central crab, because the shot blocks cannot be broken to bring a lower crab. Shoot a Super as the crab crawls on the side of the blocks near the top door, then freeze it mid-air pixel perfectly. Perform a tight down grab to get onto it then jump through the door shell. Knocking the crab off while it is on the the door or ceiling will not work.

Entrance condition:

{
  "comeInWithGMode": {
    "mode": "indirect",
    "morphed": false
  },
  "comesThroughToilet": "any"
}

Requires:

{
  "notable": "Crab High Pixel Ice Clip Door Lock Skip"
}
"canTrickyGMode"
{
  "ammo": {
    "type": "Super",
    "count": 2
  }
}
"h_highPixelIceClip"

Exit condition:

{
  "leaveWithGMode": {
    "morphed": false
  }
}

Bypasses door shell: true

Dev note: This is only for indirect G-Mode, because it is trivial while in direct, and would use a different strat.
