Green Pirates Shaft: Grapple Teleport (from Red Brinstar Firefleas)

Room ID: 21

Wiki
From: 4
Bottom Right Door
To: 1
Top Right Door

In Red Brinstar Firefleas, instead of simply grappling and moonwalking into the transition, perform a setup like in the Moat: Angle-up, jump, bonk the ceiling, then use Grapple just before landing and moonwalk back as it attaches. This will put Samus into a lower position after the transition. Samus will be stuck inside the wall. Perform a Crystal Flash, then morph and roll out.

Entrance condition:

{
  "comeInWithGrappleTeleport": {
    "blockPositions": [

        5,
        3
      ]
    ]
  }
}

Requires:

"canInsaneJump"
"h_canCrystalFlash"
