Mosley came to Perfection to be a pupil of the Burt's survival school in the Tremors: The Series episode Blast from the Past. He had gone there with his friend Rosser. During his visit there was an Ass Blaster attack. The Ass Blaster turned out to be the one that Nancy had sold to Sigmund and Ray at the end of Tremors 3: Back to Perfection and had escaped. With the help of the townspeople, Rosser, Brock and Mead Mosley cooked up meals to attract Messerschmitt, allowing it to be captured.
