Ghost stories aren't the only things to be afraid of at the Pony Tails' big Halloween party

The Pony Tails—Corey, May, and Jasmine—are planning a big party for Halloween, and Corey can't wait to host it. But in the days leading up to the event, Corey's pony Samurai starts acting strange. Samurai seems to get spooked whenever he is around a pony named Midnight—a gray who, according to some, could be bad luck. With black cats crossing their paths and the weather report calling for a big thunderstorm on the big night, the Pony Tails wonder if there's any truth to superstition.

Will the girls be able to save their party from the spooky forces that seem to be all around them?
