The Incredible Voyage of Mark O'Gulliver 1967

Animation sponsored by the U.S. Chamber of Commerce on the problems posed by big government. Congressman Mark O'Gulliver finds himself stranded in Animalia, a remote island in the Pacific inhabited by talking, clothed rabbits, bears, lions, hippos, and other animals. The island government mirrors that of the United States, and O'Gulliver has issues finding his way home due to stuffy bureaucracy.
