In addition to his drinking problem, Champ is also a compulsive gambler, another vice which he repeatedly promises Dink he will surrender (but never does). After a winning streak, he fulfills a previous promise to buy Dink a pony, whom they subsequently name "Little Champ" and decide to enter into a race. At the track, Dink happens across a woman who, unknown to either of them, is actually his mother Linda. She is now remarried to Tony, a wealthy man who owns one of the other horses in the race.
