Freeze the left-most Zeb while it is rising and is 1 pixel too low from making a flat runway. When it is close to thawing, run into the thorns to the left and hold left to avoid a vertical damage boost, then refreeze the Zeb as it crosses. It will now be 1 pixel higher. Freeze the Zeb again once it is in the perfect position to bridge the gap, which has a 2-3 pixel range.

Requires:

{
  "notable": "Frozen Zeb Runway"
}
"canTrickyJump"
"h_trickyFrozenEnemyRunway"
{
  "thornHits": 2
}

Exit condition:

{
  "leaveWithRunway": {
    "length": 6,
    "openEnd": 1
  }
}

Dev note: It is possible to farm another zeb and return and refreeze this Zeb to leave with full Energy, but that is not assumed here. FIXME: This could be done to extend the runway out of the right door as well, but it would only add 1 tile and is a pain.
