The Incredible Space Circus

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.
