Osceola and Renegade
The Osceola and Renegade mascots were conceived by Bill Durham, a Tallahassee businessman and Florida State alumnus. He came up with the concept of a horseback-riding Seminole mascot as early as 1962, when he was voted into the school's homecoming court. He returned to the idea in 1977, and won the support of Ann Bowden, wife of head football coach Bobby Bowden, who helped make the idea a reality. Durham contacted the Seminole Tribe of Florida about the project, and chairman Howard Tommie had tribe members make the first costume for Osceola. Durham provided the horse, while Bowden helped acquire the various permits necessary to allow a horse onto the field.
University of Oregon
The mascot of the University of Oregon is the fighting duck. The popular Disney character Donald Duck has been the mascot for decades, thanks to a handshake agreement between then-Athletic Director Leo Harris and Walt Disney in 1947. The mascot has been challenged more than a few times in its lifetime. The first came in 1966 when Walt Disney died and the company realized there was no formal contract written for the use of Donald's image. A formal contract was written up in 1973. Potential heirs "Mallard Drake" and "Mandrake" challenged Donald's position in 1978 and 2003 respectively, but both were unpopular and discontinued.
