Mirror, mirror on the wall. Who has the best costume of them all?
That's the question the first annual Hub Halloween Bash aims to answer. The two-hour special, hosted by Saturday Night Live's Kenan Thompson, features children from across the country competing in a star-studded costume contest with the winner nabbing $25,000 and a walk-on role on the Daytime Emmy-winning series R.L. Stine's The Haunting Hour: The Series.
