Far-off planet (Dr. Tenth)

The Tenth Doctor went to a "Far-off planet" for a holiday, but his peace was interrupted by a Sontaran invasion, or specifically Sontaran 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 both of them sat down with the other Sontarans for lunch. (PROSE: Dr. Tenth)
