Butch Cassidy and the Sundance Kid are two historical outlaws who appear in The Prisoner of White Agony Creek.

When Bat Masterson, Wyatt Earp and Roy Bean arrive to Dawson to catch the then young Scrooge McDuck, they find Butch and Sundance, who accept to help them with the hidden intention of stealing Scrooge's goose egg nugget. Sundance Kid steals two sleds top go there (without thelling the lawmen they are stolen, of course) and go to Scrooge's claim. While Scrooge is busy facing the three lawmen, Butch and Sundance take the nugget alongside Glittering Goldie as a hostage. Scrooge rides two caribou to reach their sled and when the Sundance Kid tries to shoot him, he causes an avalanche. The ice breaks and the caribou save Scrooge and Goldie, but Scrooge then returns to the sled, albeit he only saves the sled dogs while Butch Cassidy and the Sundance Kid are greeted by a waterfall.
