Requires a runway of at least 6 tiles (with no open end) in the adjacent room. Use a Cross Room Jump into Water followed by a delayed Momentum Conserving Turnaround. Then morph and move right to go through the Morph tunnel above, avoiding damage from the crab. With the minimal runway length, this requires precise timing.

Entrance condition:

  }
