Puft Marshmallow Man is destroyed there is a shot of  a man down on the street being deluged by a huge amount of  marshmallow goo. Due to the extreme angle of the shot most viewers  dont realize that this is Walter Peck. A cut scene (included on the  DVD) took place a few moments before, at the same angle, where Peck  tells the police to go up to the roof and arrest the Ghostbusters.
