The Stay-Puft Marshmallow Man is a fictional character from the Ghostbusters franchise, who sometimes appears as a giant, lumbering, and paranormal monster. He first appears in the 1984 Ghostbusters film as a logo on a bag of marshmallows in Dana Barrett's apartment, on an advertisement on a building near the Ghostbusters' headquarters, and finally as the physical manifestation and form of the apocalyptic Sumerian deity Gozer.
Gozer returns in this form multiple times; however, the Stay-Puft Marshmallow Man in The Real Ghostbusters animated series is the manifestation of the dream of a child holding a bag of Stay-Puft Marshmallows during the attack by the Sandman.
Subsequently, he has been incorporated into many other types of Ghostbusters media, including the animated series The Real Ghostbusters, comic books, a stage show, and several video games.
