‘Ghostbusters: Afterlife': See Stay-Puft Marshmallow Man Get Miniaturized and Multiplied (Video) Meet the Mini-Pufts — they’re cute but definitely not sweetLawrence Yee | April 7, 2021 @ 7:45 AM Last Updated: April 7, 2021 @ 8:07 AM The Stay-Puft Marshmallow Man is returning to the “Ghostbusters” movie franchise — the time in miniature form. In a new clip for “Ghostbusters: Afterlife,” Paul Rudd’s character meets the mini version of the giant monster that terrorized New York in the original 1984 film. Rudd is seen loading up on ice cream in a grocery store when he decides he needs some toppings. He heads to the aisle where they’re stored, where a Mini-Puft tears itself out of its packaging.
