This results in a basketball game and Swackhammer later comes to earth to watch the Nerdlucks now Monstars and the Looney Tunes play basketball as the Monstars coach.

Michael Jordan makes a deal with him that if the Monstars win, Swackhammer would spare the Looney Tunes in exchange for his own freedom as his newest attraction in Moron Mountain. He readily accepts it, thinking of the possibilites of Jordan as his newest attraction, playing basketball with his customers while chained up meaning he would always lose no matter what he did.

However, the Monstars lost to the Looney Tunes resulting in Mr. Swackhammer being furious because of the loss. The Monstars told Michael Jordan they were afraid of Mr. Swackhammer until they realize they had grown much bigger than him. They turned on Mr. Swackhammer and decided to strap him to a rocket sending him straight to the moon. Due to being Swackhammer being stranded on the moon, Moron Mountain was presumably shut down.
