The Grizzlies continued to use live bears as mascots until the early 1960s. In addition to Teddy, there was a Cocoa, a Chester, and three different Fessy's (named after former football coach Doug Fessenden), among several others. In the 1970s and 1980s costumed mascots were introduced, but as mascots of local sponsors, not the university.
Later in the 1980s, a costumed mascot by the name of Grizzly Otto (after local sponsor Grizzly Auto) was introduced as part of the Montana cheer squad. The current mascot, Monte (short for Montana), was introduced in 1993 and in 2002 became the first winner of the Capital One Bowl's "Mascot of the Year" contest. He won again in 2004 and was nominated three other times.
