Spook-a-Rama: The Spook-a-Rama is a dark ride from the Pretzel Amusement Ride Company located at Deno's Wonder Wheel Amusement Park on Coney Island and run by Million Amusement Corp..  The rider is pulled around in a car resembling an old wooden barrel.  These barrels look like connected cars, but separate from each other at the beginning of the ride, so the rider must go in alone, passing paintings that change imagery, and a skeleton before the car itself forces the doors open.  Inside, the ride is one large, poorly lit room.  The ride recently had a major renovation done by Scarefactory inc. and more information will surface with the opening of Deno's Wonder Wheel Amusement Park for the 2013 season.
