A height chart for the characters featured in Spooky Month 6: Hollow Sorrows
Several of the characters are blacked out, including Michelle (between Father Gregor and Dexter), Garcia (between Mayor Evermore and Rick Hedony), Mort Vivifico (between Ignacio and Frank) and possessed Patty (next to Frank at the end of the lineup)
The tall shadow next to Jack is most likely Moloch lacking all his features minus his broad shoulders and rectangular head. This was likely done to keep his full design a secret until the release of the episode, though it's currently unconfirmed.
