Malice in Aqualand

While participating in a rodeo at Aqualand's theme land Westernland, Jabberjaw sees Dr. Cybron's henchmen kidnap the Rajah and replace him with a robot duplicate. He tells The Neptunes and Dr. Cybron tries to silence them by sending a runaway stagecoach over a cliff. When that plot fails, his henchmen capture Bubbles and send a duplicate of her to capture the others. The group rescues Bubbles and the Rajah and discovers that Dr. Cybron himself is a robot.
