They are greeted only by two different types of robots: swarm robots (Vardies) and slow but sentient emojibots . An emojibot gives the Doctor and Bill discs that communicate their true emotions . The Doctor theorizes that the planet is awaiting the colonists but soon realizes that the setup crew has been killed by emojibots and their skeletons crushed to feed the plants . Determined to blow up the city, he finds the main ship within it and its engine room, but Bill runs into a child who has awoken from a pod . The colonists were cryogenically frozen, with a few "shepherds" woken early to work . After one shepherd died, the emojibots could not recognise grief and killed all in mourning in an onslaught against sadness . The awakened colonists decide to fight back, but the Doctor wipes the memory of the robots and reboots everything...only humans must now learn to live with the Vardies, the planet's indigenous species . When the TARDIS returns the Doctor and Bill to London, they discover themselves on a frozen Thames River, with an elephant walking towards them on the ice . </Td> </Tr>
