Frank Baum's Oz Wizard of Oz series, one of the most famous children's fantasy series to be adapted to screen. Guns actually do feature in multiple works in L.
Thus, other than the Scarecrow's gun, most of the weapons seem to have a specific purpose in the film instead of just being a prop. The only remaining reference to the scene is when the Wicked Witch sends her flying monkeys to capture Dorothy, revealing she already sent a bug to tire them out. The Lion's bug spray and net seem to be held over from a previously deleted 'Jitterbug' scene - an elaborate song-and-dance number intended to capitalize on the Jitterbug craze at the time.
For example, the Tin Man's axe is one he has had throughout the film. Some of the weapons in the Haunted Forest scene might seem nonsensical, but most of them do have an explanation. Thus, guns in the land of Oz seem to have a more ornamental purpose rather than actually being used as tools of warfare. However, when the Wicked Witch of the West suddenly appears in a cloud of smoke, the Munchkins don't bother to get off a shot. During the early scene in Munchkin Land, there are armed Munchkin guards with rifles and bayonets. The Scarecrow isn't the only one carrying a gun.
