Ramsay, Tricey and Sexy.
And their tiny Doctors.Okay, I guess a wee explanation is due.
Ramsay the Vortisaur had first appeared in the Eighth Doctor’s audio “Storm Warning” and became the temporary TARDIS team pet.
Tricey the Triceratops starred as herself alongside Eleven in “Dinosaurs on the Spaceship”.
And the T-Rex had greatly impressed the freshly regenerated Twelvey, hence the name.
