Very little is known about Snowball, except that he appears to be a breed of draft horse, built as muscular, and hulking. He is loyal to his master, however, can not be considered truly evil as he does not have a human-based personality like other animals in Disney films are sometimes seen to have.
Role in the film
In the audio commentary of the DVD, film directors, Kirk Wise and Gary Trousdale and film producer, Don Hahn reveal the real name of Frollo's horse, Snowball. He appears only a handful of times in the film. His final fate is unknown, but one of the few things that happen to him is when Esmeralda throws a stone at his butt thrusting Frollo off.
