Zocci

Zocci were the species to which Bannakaffalatta belonged. (TV: The End of Time) Zocci were small, red humanoids with spiked heads. (TV: Voyage of the Damned)

They looked similar to the Vinvocci. However, the Vinvocci pointed out that they and the Zocci were different, sounding quite annoyed when the Tenth Doctor compared them to Bannakaffalatta. (TV: The End of Time)

The Eighth Doctor aided a Zocci friend after his dodgy planetary hopper crashed on Carolian IV. The merchant who sold him the hopper, Jinko, refused to refund the Zocci's grotzits. The Doctor used his sonic screwdriver to reduce Jinko's merchandise to molten metal. (PROSE: The Red Bicycle)

Behind the scenes

 * The name of Bannakaffalatta's species was never specified in Voyage of the Damned but was identified by Russell T Davies. The name was confirmed on-screen in The End of Time, by a member of a similar-looking species.
 * RTD suggested the Zocci and Vinvocci might be related species. (CON: Lords and Masters)
 * J. K. Woodward, who worked on the Star Trek crossover Assimilation², released a piece depicting Bannakaffalatta assimilated by the Borg.
