The goblin ship was a spaceship that a group of time-riding Goblins used to travel through time to steal babies that were interwoven with coincidences and luck. The more coincidences that occurred, the more the ship could travel in time and create alternate timelines. (TV: The Church on Ruby Road [+]Russell T Davies, Doctor Who Christmas Special 2023 (BBC One and Disney+, 2023).)
The Fifteenth Doctor inferred that the Goblins and their ship were "the legacy" of the Toymaker, whose legions had followed him (PROSE: The Church on Ruby Road [+]Esmie Jikiemi-Pearson, adapted from The Church on Ruby Road (Russell T Davies), BBC Books novelisations (BBC Books, 2024). Chapter Thirteen; Page 100.) into the universe after the Fourteenth Doctor inadvertently summoned him by invoking a superstition at the edge of the universe. (TV: Wild Blue Yonder [+]Russell T Davies, Doctor Who 2023 specials (BBC One and Disney+, 2023)., The Giggle [+]Russell T Davies, Doctor Who 2023 specials (BBC One and Disney+, 2023).)
On board the ship, it had doors, a ventilation system, a holding cell for prisoners and a canteen area where the Goblin King ate the babies his followers brought before him, which also had a stage that the Goblin band used to perform for the King as he ate. As the Doctor deduced, he and Ruby Sunday could use the rope to travel through the ship and also disable it completely by unhooking the master rope as they recued Lulubelle on Christmas Eve, 2023.
The ship seemingly disintegrated when the Doctor weighted down the shop with his intelligent gloves so that the spire of the church on Ruby Road pierced the ship, and the Goblin King as well, in 2004. (TV: The Church on Ruby Road [+]Russell T Davies, Doctor Who Christmas Special 2023 (BBC One and Disney+, 2023).) As the Doctor negated the cracked timeline created by the Goblins, they themselves faded from view, as though they had been erased from existence or pulled back into another world.
