Wait for the first Kihunter to pass and then run through the remaining two. A second hit can be avoided by moving quickly and using i-frames from the first hit.

Requires:

{
  "heatFrames": 480
}
"canDash"
{
  "or": [
    {
      "enemyDamage": {
        "enemy": "Kihunter (red)",
        "type": "contact",
        "hits": 2
      }
    },
    {
      "and": [
        {
          "enemyDamage": {
            "enemy": "Kihunter (red)",
            "type": "contact",
            "hits": 1
          }
        },
        "canUseIFrames"
      ]
    }
  ]
}

Dev note: FIXME: this includes waiting for the acid cycle (in case of needing to go right). Otherwise it could be done with 380 heat frames.
