In this week’s “Disney Parks After Dark” series, we’re switching it up and offering a video look inside Magic Kingdom Park after hours that only we could dare to get.

The first Mickey’s Not-So-Scary Halloween Party of the season will officially return tomorrow night, but it appears some of the residents of the Haunted Mansion have been preparing to step out in Mickey’s “Boo-to-You” Parade. We caught them practicing on Main Street, U.S.A. at the witching hour of midnight, of course.

Check out the video above to watch the Gravediggers perfect their spine-tingling delights.
