Far-off planet (Dr. Tenth)

The Tenth Doctor visited a "far-off planet" with two suns for a holiday, but his peace was interrupted by a Sontaran invasion led by General Staal. After saving him from an Ogron, the Doctor learned the Sontarans wanted to invade the planet because they were fond of the planet's sausages, which they believed to be the best "in the whole of the universe". After the Doctor convinced Staal that they didn't need to invade the planet to continue enjoying their sausages, the two of them sat down with the other Sontarans for lunch. (PROSE: Dr. Tenth)
