Pete-Roleum and His Cousins

Pete-Roleum and His Cousins (1939) is a family, animation directed by Joseph Losey rated 7.7/10.

Pete Roleum, an oil droplet, narrates a presentation about the history and uses of oil: He starts by introducing some of his relations, with illustrations of the things that they have done throughout history. He then turns to the modern era, and shows that oil has a great many important uses, some of which might come as something of a surprise.
