The Lone Stranger and Porky.

The Lone Stranger is sleeping when his faithful, if overly caricatured, Indian scout sees stagecoach driver Porky being robbed by a bad guy. The scout summons the Lone Stranger, who rides to the rescue. The bad guy goes after him (and, briefly, the narrator). But just in the nick of time, the Lone Stranger recovers and conquers the bad guy. Meanwhile, Silver and the villain's horse have been having their own close encounter, and Silver returns with several little colts.
