Thumper is a skiing instructor who appears in the Season Six episode, "Asspen", where he was initially seen instructing Stan Marsh, Kyle and Ike Broflovski, Eric Cartman, and Butters Stotch the basics of skiing. After being challenged by Tad Mikowsky, Stan asked Thumper for help learning how to ski. During a montage, Thumper was able to improve Stan's skiing skills enough for him to win the race down the K-13.
