Following his third Championship victory with the Chicago Bulls, basketball star and living legend Michael Jordan decides to retire and follow in his late father's footsteps, dedicating himself to becoming a baseball player. However despite his best attempts, it's clear that his prodigious basketball skills do not translate to the baseball diamond.
Meanwhile the faltering space amusement theme park Moron Mountain run by the villainous Swackhammer is in danger of closing down because its too stale and boring. He needs something new, something fresh, something ... looney. And so the ruthless Swackhammer decides to "recruit" the Looney Toons. He sends his inept henchmen, the Nerdlucks to Earth to bring the cartoon characters to Moron Mountain as his new star attractions by any means necessary!
Despite the Nerdlucks' alien technological superiority, the wily Bugs Bunny tricks them into a contest where their diminutive size, slow speed, and clumsiness gives them a major handicap. In essence: basketball!
All seems well for the Looney Toons until the Nerdlucks steal the basketball prowess from Earth's greatest NBA players and transforming them into hulking monstrosities with the awesome skills of Charles Barkley, Patrick Ewing, Muggsy Bogues, Shawn Bradley, and Larry Johnson. Realizing that they are outclassed by these new Monstars, Bugs Bunny turns to the Looney Toons' only hope from eternal slavery at Moron Mountain. The one man who can match the Monstars' peerless skills on the court ... Michael Jordan to coach them.
