It is not suitable for a Spengler to be anything as unscientific as a Ghostbuster, at least in the eyes of Egon's Uncle Cyrus. Egon has to reluctantly go back to the midwest, over 1500 miles from New York, and feed mice at the Spengler Labs, but the Ghostbusters will try anything to convince Uncle Cyrus that there actually are such things as ghosts. But things get out of hand when Uncle Cyrus unwittingly lets the Staypuft Marshmallow Man out of the Containment Unit, and the Ghostbusters have to put him back before he destroys the city again.
