Stay Puft Marshmallow Man

The Stay-Puft Marshmallow Man is a fictional character from the Ghostbusters franchise, who appears as a giant, lumbering, and paranormal fluffy monster with a cute but also creepy looking smile on his face. 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.
