I was going to (and still could someday) add an update to the site (away from the old Tobins Spirit Guide) which would have included Mr. Stay-Puft. C’mon, this is the Stay Puft Marshmallow Man! With a refresh underway it was the right time to recall where he came from, what he is and talk about his accomplishments.
Post Update: When I made the decision to evolve Ecto-Containment to an overall Ghostbusters web sites, pages such as the friendly ghosts page were removed.
