If entering the transition too deeply, Samus may end up stuck slightly inside the Bomb blocks and the floor. This can be avoided by tapping up to retract Grapple (pulling Samus left and down), holding left while releasing Grapple, then jumping to clip up through the floor. If Morph is available, rolling out to the left is also an option.

Entrance condition:

  "comeInWithGrappleTeleport": {
    "blockPositions": [

    ]
  }
}
