The Kihunters can be killed by retreating to the morph tunnel if needed.

Entrance condition:

{
  "comeInGettingBlueSpeed": {
    "length": 3,
    "openEnd": 1,
    "maxExtraRunSpeed": "$1.8"
  }
}

Requires:

"canSpeedball"

Clears obstacles: B, C

Dev note: There is 1 unusable tile in this runway. This can also work at higher run speeds, at least up to $2.A, but this is more difficult and the usable runway would be less.
