Youppi! is the official mascot for the NHL’s Montreal Canadiens and former longtime mascot of the MLB’s Montreal Expos (now the Washington Nationals). Youppi! was commissioned by the Montreal Expos and originally leased by the team. In 1979, the mascot was purchased by the Expos baseball team and represented them until they moved to Washington, D.C., after the 2004 season. The orange, hairy giant was one of the most popular figures among everyone at Olympic Stadium, where he was often seen running around with his arms waving wildly during baseball games.
P.S. Youppi! was designed by Bonnie Erickson, formerly a designer for Jim Henson, and the designer of Miss Piggy, Statler and Waldorf and other Muppets characters. Youppi! is one of only three mascots inducted to the Baseball Hall of Fame. The other two are the Phillie Phanatic, another Erickson design, and the Famous San Diego Chicken.
