Osceola and Renegade
Osceola and Renegade are the official mascots of the Florida State University Seminoles. Osceola, representing the historical Seminole leader Osceola, and his Appaloosa horse Renegade introduce home football games by riding to midfield with a burning spear and planting it in the turf.
American alligator
"Gators" has been the nickname of the University of Florida's sports teams since 1911. In that year, a printer made a spur-of-the-moment decision to print an alligator emblem on a shipment of the school's football pennants. The mascot stuck, perhaps because the team captain's nickname was Gator.
