Speelfox

A Speelfox was a creature about which the Sontarans knew. Evidently, they fed on slimebait. 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.
