Slimebait

Slimebait was a type of creature that the Sontarans knew well. Evidently, they were preyed upon by the Speelfox. During the 2009 Sontaran invasion of Earth, Commander Skorr of the Tenth Sontaran Battle Fleet observed that human UNIT soldiers, who had been disarmed by the Sontarans' cordolaine signal, ran like slimebait from a speelfox.
