A crooked space circus proprietor, Zarnum, uses a device to turn protected animals that have been illegally captured into beasts to boost attendance at his space circus. Sensing that the Super Friends are on to his scheme, he uses the device to change Wonder Woman, Aquaman, and the Wonder Twins into space creatures. It is up to the rest of the Super Friends to track down the elusive space circus, rescue the captive Super Friends, and bring an end to the poaching that has been taking place. 
NOTE: Zarnum's name is loosely based on circus legend P.T. Barnum.

Batman and Robin head off to a planet named Texarkana after receiving a distress alert that a local villain, the Capricorn Kid, is terrorizing the planet. After defeating the Kid and putting him in jail, the Kid vows revenge. He and his group of outlaws travel to Earth, break into the Hall of Justice, and plot their revenge on all the Super Friends. The Kid's group successfully places each of the Super Friends in dangerous situations and they deliberately force Batman and Robin into freeing each person...but the catch is that each trap is timed and the object of the game is to free all the Super Friends from the various traps before it is too late. In a showdown, Batman and the Kid meet up in an old-fashioned shootout.
