While working in Stampede Wrestling, for Stu Hart Tattrie met Josip Peruzovic (better known in pro wrestling as Nikolai Volkoff). Tattrie took Peruzovic under his wing as a protégé and alongside Stu Hart trained the non-English speaking, 315 pound man to become a professional wrestler. Tattrie became known as Geto Mongol and Peruzovic as Bepo Mongol; together they were the Mongols. They had a very unorthodox appearance with bald heads and little "horns" of hair on the very top of their skulls.
