I just saw something very cool on ology.com; real Stay Puft Marshmallows themed after the Stay Puft Marshmallow Man from the Ghostbusters movie and animated series. Not much more to say than awesome! They are selling this fairly large box for about $20 bucks and although I am sure the Stay Puft marshmallows taste great this is more intended for collectible purposes. The site has a great description of the Stay Puft character and gives him plenty of villainous props. I would recommend checking out the site and looking for this product in comic stores, hobby shops, or online retailers.
