Entrance condition:

{
  "comeInWithGMode": {
    "mode": "any",
    "morphed": true
  }
}

Requires:

"canOffScreenMovement"
"h_canArtificialMorphIBJ"
{
  "or": [
    "h_canArtificialMorphSpringBall",
    "Gravity"
  ]
}

Dev note: Spring Ball and Gravity wouldn't be required with some risky off-screen horizontal bomb jumps. This strat is only useful for avoiding a wall jump. A simpler variant exits G-Mode after the morph tunnel.
