In a new episode of "Sonny With A Chance," NBA superstar Shaquille O'Neal hosts a ghoulish "So Random!" Halloween special, with musical guests Allstar Weekend and a brand new song performed by the show's star, Sonny Munroe.

The special Halloween episode airs Sunday, October 17 at 8pm on Disney Channel.

"Sonny With A Chance" is a sitcom about Allison "Sonny" Munroe, a talented Midwestern girl who, after posting her homemade comedy videos online, is discovered by a television producer and gets the chance to star in "So Random!," the most popular sketch comedy series for kids and tween. She relocates to California with her mother but her bubbly personality clashes with the resident queen of the cast, Tawni Hart.

Rounding out the "So Random!" cast is the quirky and original Zora, the confident and cool Nico and his sidekick, the gregarious, fearless Grady.
