Sioux Me is a 1939 Merrie Melodies cartoon directed by Ben Hardaway and Cal Dalton. It's released on September 9, 1939.
An Indian reservation is experiencing the worst drought in a decade. The Indian chief enlists the help of a rain dancer. The chief's son happens upon (and buys) a set of weather pills which can bring rain, ice, lightning, earthquakes and other natural phenomena. Where these pills end up supplies much of the humor.
