Plot hole: The Ghostbusters cross their proton pack streams which results in a tremendous explosion. The next scene shows the blast pushing Mr. Sta-Puft away from the building. A second later another scene shows the explosion radiating outward from the roof. The only part of him shown over the edge of the building is his head and his right hand. To get all over the Ghostbusters, marshmallow would have to be blown in the opposite direction against the force of the blast. It makes sense that there was marshmallow all over the street, but how did it land on the Ghostbusters?Grumpy Scot
