Stay Puft Marshmallows are a fictional food in the Ghostbusters franchise. Their mascot is the Stay Puft Marshmallow Man.
Primary Canon HistoryEdit
Some time during Ray Stantz' youth, he roasted Stay Puft Marshmallows and it remained his most fondest childhood memory.
In 1984, when Dana Barrett first encounters Zuul, her abandoned groceries included a bag of the marshmallows and some time later, a sign advertising them can be seen when the Storage facility explodes.
Secondary Canon HistoryEdit
Legion Mini SeriesEdit
After the Ghost of Christmas Past transports the Ghostbusters and Woodrow Wainwright Fraser III to Camp Waconda, they witness a young Ray with his parents roasting Stay Puft Marshmallows. Ray also appears to keep a bag on his nightstand in the Firehouse sleeping quarters. Some marshmallows are present in the apartment where Janine Melnitz's team's first bust took place. Dana also still keeps a bag in her kitchen.

Paragraph reads: "A large billboard -- rendered in matte painting form by Matthew Yuricich -- appears on one of the buildings adjacent to the firehall. Featured on it is a representation of the Stay-Puft marshmallow man and the words "Stay-Puft Marshmallows -- Stays Puft, Even When Toasted" -- an advertising slogan lifted from Dan Aykroyd's original script."

Michael Gross recounts: "In fact, at one point, we considered either ending or beginning the Ghostbusters commercial with a Stay-Puft spot -- complete with a little stop-motion countertop like the Pillsbury doughboy. We discarded that idea, though, as being a bit of overkill."

Ghostbusters: The Video Game (Realistic Versions) - Firehouse (2009) (PC/PS3/Xbox 360). Terminal Reality. Rennie Handrahan says: "Rennie Handrahan with Comm Core Corp. Stay Puft Marshmallows are one of the many high quality products we make here at Comm Core. Frankly, we're outraged. You may have fooled the city with your little puppet show but not us! This company has worked over 75 years to cultivate the family friendly image of Mr. Stay Puft. He was modeled after somebody's uncle for crying out loud! And it wasn't all so you could go to war with him in downtown Manhattan! This is defamation of character on the grandest scale! You'll be hearing from us Ghostbusters! Have a sunny, funny Comm Core Corp day."
