It was the first Doctor Who spin-off to produce a special for Comic Relief and was broadcast on 13 March 2009 as part of Red Nose Day 2009.

Mr Smith identifies the disturbance as a teleport and a diplomat named Ranius (played by comedian Ronnie Corbett) appears.

Sarah Jane, Clyde, Rani and Luke all notice the similarity of the constant flatulence with that of a Slitheen wearing a skin suit, which Ranius denies quite strongly.

The story Ambassador Rani tells is also a reference to The Two Ronnies – both the visual of Corbett sitting in the chair and his mention of "Fork Handles" (or Four Candles).

The gifts bestowed on Sarah and her friends are Comic Relief deely boppers, and the final shot of the scene is K-9 sporting a Red Nose.
