Screamer (The Daleks' Master Plan)

Screamers were nocturnal, bat-like creatures native to Desperus. Named for their loud screeching, they frequently attacked the criminals stranded on that planet. They attacked Bors, Garge and Kirksen (the last was terrified of them) when they left their cave to investigate the landing of the Spar. (TV: The Daleks' Master Plan)
