The ghosts decide to celebrate Christmas by having a trip to the Moon but things go wrong when a strange space ship pursues them. Their powers are no use and they are all captured - except for John, left alone on the Moon. However, the Constellations themselves come to help him and John sees Orion the Hunter, the Great Bear, the Crab and the Unicorn pursue the rocket ship. At last Draco the Dragon is released and thunders across space. The Ghosts are saved and so is Christmas.
