After attending a meeting with his support group, Earthbound Birds Anonymous, Opus decides "to take the laws of physics into his own hands" and goes to a balloon shop, where he begins his attempt to become an "aeronautic vigilante." He puts on a girdle and, with help from his friend Bill the Cat, attaches balloons to it. But Bill's tongue gets stuck to the girdle Opus is wearing, causing his attempt at flight to go out of control and eventually have a crash landing. Opus is so upset at this that he chastises Bill for it, hurting the cat's feelings.
