Freeze a crab at a very precise position in order to clip through the center Morph tunnel without a way to see. Use a frozen crab on the opposite wall in order to better time the crab being used for clipping and as a way to climb on top of it. Ice Beam on its own has a high chance of hitting a wall instead of the crab; straight vertical shots can help. Gravity has a 2 pixel clip window while Suitless there is only 1 pixel up higher which requires a precise down grab to get onto the crab.

Requires:

{
  "notable": "Ice Clip"
}
"h_navigateUnderwater"
"canOffScreenMovement"
{
  "or": [
    {
      "and": [
        "Gravity",
        "h_preciseIceClip"
      ]
    },
    {
      "and": [
        "HiJump",
        "h_highPixelIceClip",
        "canBeVeryPatient",
        {
          "or": [
            "HiJump",
            "Gravity"
          ]
        },
        "h_trickyToCarryFlashSuit"
      ]
    }
  ]
}

Dev note: FIXME: It is possible to crab climb with nothing but ice and walljumps.
