Ponyboy describes Mickey Mouse to Cherry Valance in Chapter Three of The Outsiders. Pony had never "old anyone about Soda's horse. It was personal," but he finds himself opening up to Cherry (39). Ponyboy's description of Mickey Mouse perfectly characterizes the kind of a relationship a boy can have with a horse and the love that Sodapop had for Mickey Mouse.
According to Ponyboy, Mickey Mouse was one "ornery pony," but Sodapop loved him for it (39). The horse would only come when Soda called him, and even though Mickey was down right mean to everybody else, he and Soda shared a bond. Ponyboy recalls, "He may have belonged to another guy, but he was Soda's horse" (40).
Unfortunately, Mickey's owner sold him, and when Soda found out, he "had bawled all night long" (40). Soda had never really wanted anything for himself, but he had wanted Mickey Mouse.
In Chapter 3 after the drive-in movie is ended, Ponyboy, Johnny, and Two-Bit offer to give Marcia and Cherry a ride home. So, they all walk to get Two-Bit's car.
As they walk along, Ponyboy finds it very easy to talk with Cherry.
The first thing I knew I was telling her about Mickey Mouse, Soda's horse. I had never told anyone about Soda's horse. It was personal.
Mickey Mouse was a beautiful dark-gold buckskin quarter horse at the stables where Soda once worked. Ponyboy narrates that although Soda did not own the horse, "Mickey Mouse was Soda's horse"; in other words, there was a communication between Soda and this horse. Ponyboy describes Soda as being "crazy about Mickey Mouse" because he would come whenever Soda called, and he would nibble on Soda's sleeve. But, he would not do these things for other people, not even the owner. With other horses, Mickey Mouse was aggressive; however, at all times he was tractable with Soda, only giving him a light nip once and a while. But, sadly for Soda, Mickey Mouse was sold, and one day the new owners came and took the handsome horse. Only thirteen at the time, Soda cried all night long because of his loss of a kindred spirit.
