Requires a very precise runway length in the previous room of 15 tiles with no open end. Jump while under or to the right of the Bull. Samus's speed no longer changes once hitting the water, so the jump is very forgiving, while the runway length is not.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": true,
    "minTiles": 14.4375
  }
}

Requires:
