"A Scooby-Doo Halloween" is a Halloween special of the animated TV series What's New, Scooby-Doo? It first aired in the United States on The WB Television Network on October 25, 2003.
In this Halloween special, the Scooby Gang heads to the eerie town of Banning Junction to spend Halloween with Velma's aunt, uncle and the beautiful and flirtatious cousin Marcy. The gang joins the townspeople in celebrating their renowned "100 Years of Halloween" festivities, including a crowning of the Queen of the Masquerade Ball and an amped out performance by KISS.
When strange and spine-tingling things begin to happen, a fearful townswoman blames it on the ghost of Hank Banning, the town's founder and ousted mayor, back to seek revenge on the town that wronged him one hundred years earlier. While Shaggy and Scooby anxiously wait to meet KISS, go trick-or-treating for tons of candy and have not regular scary, but Halloween scary- fun, they reluctantly aid Fred, Daphne and Velma in putting their investigative skills to work in hopes of revealing who is really behind the Halloween mischief.
