A mid-1990s cartoon based on the infamous Mutant League Football and Mutant League Hockey games by Electronic Arts depicting monsters playing pro sports. An earthquake at a football stadium reveals a cache of illegally dumped toxic waste which mutates all the spectators into half-human abominations. Soon a pro sports league springs up around the mutants, and rather than make the big bucks, rookie athlete Bones Justice decides to play for his dad's team, the last-place Midway Monsters.
