The next morning the rains come in torrents. The children gather the water to fill the fixed steam accumulator. Eventually they are airborne once more, but Count Sator has become bogged in the desert. It is Carmen who realizes that they are staring at the Rosy Prize and after a wind storm which whips some of the Doctor's notes away from Sator, the children not only find the Rosy Prize, but the Salamander as well.

Sator está decidido a capturar el autobus y lo sigue con su vehículo de persecución, ya que ha conseguido un sistema para escuchar las comunicaciones de los chicos por radio con el Valle Secreto.
