Travast Polong

Travist Polong was an orange, metre-long, three-eyed slug/slater-like alien that attempted to put an unknown plot into action at an Ealing hospital. Sarah Jane Smith showed up and he ran from her and her Sonic lipstick. She later left to deal with a Berserker, but it is unknown exactly what happened to Polong. (SJA: The Mark of the Berserker)
