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.
