After being sent to the principal's office again, Rocky has one last chance to be nice around the other students rather than be a mean bully. If he fails, he will be shipped off to military school. He turns to Fred and his friends for help. Captain Caveman has come down with a cold and does everything she can to try to get rid of it without having to visit a doctor. Mr. Bad takes advantage of this by diverting Grandma Cavemom to Rock Vegas and getting rid of Captain Caveman with an anti-gravity formula.
