It is possible to run through the Yapping Maw while it is attacking a different direction. But that likely requires acid damage and isn't entirely reliable.

Requires:

{
  "obstaclesCleared": [
    "A"
  ]
}
"canMidairShinespark"
"canShinechargeMovement"
{
  "shinespark": {
    "frames": 45
  }
}
{
  "canShineCharge": {
    "usedTiles": 18,
    "openEnd": 1,
    "startingDownTiles": 0,
    "steepDownTiles": 1,
    "steepUpTiles": 2
  }
}

Exit condition:

{
  "leaveWithSpark": {
    "position": "top"
  }
}
