At Retro Con I was able to score a carded Marshmallow Mess Ray Stantz figure. This repaint figure was the Club Ecto Exclusive figure for the Ghostbusters subscription. I only paid $10, which is a steal. Since I already have the clean Ray figure I think I'll leave this guy carded.
Ray comes with a Proton Pack, Neutrino Wand, Ecto Goggles, proton stream, and marshmallow covered figure stand. All the marshmallow mess on Ray is paint work, there is no new sculpting on this figure.
