The latest instalment - again written by Chris Chibnall - features Amy (Karen Gillan), Rory (Arthur Darvill) and a popular returning monster.
The Ood's intrusion into Amy and Rory's bathroom follows yesterday's second episode, in which the Doctor (Matt Smith) stumbled into the couple's bedroom.
The first instalment of 'Pond Life' - released on Monday - saw the Time Lord meet Mata Hari and lay down backing vocals on a Dizzee Rascal track.
Doctor Who returns to BBC One and BBC America for its seventh series this Saturday (September 1).
