If there's something strange at Waterloo station, who you gonna call? Ghostbusters, obviously. If you thought you saw the Marshmallow Man from 'Ghostbusters' smashing his way through the floor at Waterloo station this morning, you'll be pleased to know that you're not still drunk from the weekend. Ahead of the release of the new 'Ghostbusters' film this Friday, Waterloo station has been decked out with eight-metre 'slime poles' and a giant sculpture of the Stay Puft Marshmallow Man. They've also been handing out business cards with a number to call for all your ghostbustin' needs.
