The Looney Tunes gang have to save themselves from aliens who want to take them back to their planet to become amusement park attractions. They figure that they can do this by challenging these short aliens to a game of basketball. Once the aliens find out that they need to be taller and more athletic in order to play the game, they steal the essence of several professional NBA players. Once they use this essence, they become the "Monstars" and are very intimidating to Bugs and the gang. So, Bugs and Daffy go into the real world and kidnap Michael Jordan to help them win this game.
