Who you gonna call? SPOILER: the babysitter.
This is a shot of puppeteer and voice actor Dan Milano's daughter dressed as the Stay Puft Marshmallow Man and about to stomp all over the Ghostbusters. Me? I only stomp on two things: spiders and bubble wrap. And a lot of times I'll miss the spider and it'll crawl under my bed and I'll have to sleep in the shower with the water running for safety.
Thanks to Nick, who's crossed the streams before and said it's not nearly as catastrophic as the movie would have you believe.
