Megaluthian slimeskimmer

Megaluthian slimeskimmers were a sentient species. At some point in history they exploded the third planet of an unspecified star system. (AUDIO: Neverland)

When he was summoned into the First Rani's trap, the Third Doctor told Victoria Waterfield that he should be taking it easy instead of bounding around like some Megaluthian slimeskimmer. (TV: Dimensions in Time)
