After entering the room, quickly leave the morph tunnel with Gravity, or quickly place a Power Bomb to kill the crab before it gets to Samus. If the morph tunnel is expanded, it it possible to roll a little to the left and wait for the crab to pass before rolling out.

The tunnel does not need to be expanded for Samus to get into the morph tunnel without getting stuck, regardless of if she has Morph or artificial morph, even in direct G-mode.

  "comeInWithGMode": {
