Mad Monster Party

Baron Boris von Frankenstein (voiced by Boris Karloff) summons all monsters to the Isle of Evil in the Caribbean Sea. The invites include Count Dracula, the Mummy, The Hunchback of Notre Dame, the Werewolf, The Invisible Man, Dr. Jekyll and Mr. Hyde. The monsters begin to arrive on the freighter that Felix Flanken is also traveling on. Felix proves to be an incompetent, asthmatic (and unsuitably kind-hearted) human, the monsters plot to eliminate him.
