Synopsis:
Batman and Robin trail a wanted crook, Albey to Koba Island. They are told the legend of a sea creature which suddenly appears and kills Albey. Batman follows the clues to learn who Albey's secret partner was until the beast returns. This time Batman and the islanders chase off the creature with torches.

Batman and Robin then follow a crook, Spence, to a hidden cavern where a robot monster is stored. Spence was Albey’s partner and killed him to prevent exposure. The second attack was done by a real beast however, so Batman uses the robot creature to fight the real one. The robot is destroyed, but the sea monster is killed as well.
