Slithergee

The Slithergee were a race of obsequious alien slugs whose home planet was destroyed.

A spacecraft carrying the Slithergee arrived in the orbit of the colony planet Puxatornee, requesting the permission to settle on the first moon. Otherwise, they would humbly threaten to declare all-out war. Interference from alternate futures — unwillingly aided by the Seventh Doctor — resulted in the creation of two timelines branching out from this event, with one timeline seeing a war being waged between the Slithergee and the human colonists that reduced Puxatornee to a radioactive cinder and the other seeing a policy of appeasement towards the Slithergee going so far that the Slithergee took complete control of the colony and prosecuted human objections as "hate crimes". (AUDIO: Flip-Flop)

It was noted that Slithergee had minor empathic abilities that stimulated peoples' guilt, essentially encouraging people to feel sorry for them (AUDIO: The Memory Box).

During Lucie Miller's travels with the Monk, she attended the final of Thordon's Got Talent, which was won by a singing member of this race. (AUDIO: The Resurrection of Mars)
