The Doctor, Amy, Rory, and new travelling companion Kevin-a cybernetic dinosaur-find a scientific crew under attack from a giant, Cthulhloid space squid! Also, the two-part 'Bodysnatchers' where the crew find themselves inside an alien asylum and discover that many of the human patients within actually house the minds of some of the Doctor's most terrifying enemies! And a special, silent Christmas story. When robots attack Santa in order to destroy Christmas, it's up to the Doctor to save the day!
