I saw this cartoon about 6 years ago as part of a collection on VHS called "The Cosmic Eye". I could never remember the title and the video store from which I rented liquidated its supply. I just rediscovered the title tonight and am thrilled. "Dig" is a great cartoon about a rock that gets picked up by a kid on a bike and helps him travel into the Earth to learn about different types of rocks. There's music which is both entertaining and hilarious. A must have for enthusiasts of bizarre and amusing cartoons. "The Cosmic Eye" available for purchase as well.
