Eddie Frank brings us a Herculoids adventure from Space Stars. Space Ghost (Gary Owens) makes a timely appearance when Zandor (Mike Road) and his crew encounter a rebel tribe of monkey people who've used a means to become "The Invisibles".
Edit: 1/28/16: The video has been deleted by YouTube.
Come to think of it, the writers may have been given some plotlines rejected from Super Friends to use for the Hercs. This should've been totally discarded.
