A standard size proton pack may not be enough to conquer the ectoplasmic might of this lumbering monolith with the devious grin. The Men's Ghostbusters Inflatable Stay Puft Costume features a white jumpsuit with attached boot covers, a large blue collar with white trim, and a red bandana accent. Of course, the real fun of this costume doesn't begin till the included battery operated fan kicks into gear and inflates the suit to a silly size. It's completed with the inclusion of a Stay Puft Marshmallow Man headpiece with a wide grin and an attached sailor's hat with a red tail. Wear this outfit to a horror themed costume party and break some of the gloom and doom with your sweet and funny attire. You can be sure that you'll stand out quite prominently in a sea of black and gray costumes.
