Big Top Scooby-Doo! (2012)

In Atlantic City, a were-wolf broke into a jewelry store, and stole a ruby necklace setting off an alarm. The creature scared off the security guard, then two policeman arrived. The duo tried to stop the hairy thief, but it was too fast for them, and escaped into the nearby hills, where it overlooked a circus. Scooby-Doo and the gang travel to Atlantic City on vacation. Fred see’s that the Brancusi Circus is in town, and enthusiastically takes them to see it. They arrive to find that the circus doesn’t open until tomorrow, but decide to look around when they notice that the front door is unlocked. Whilst searching, they meet a man who is pursuing a werewolf that has intruded into the circus. The werewolf attacks the gang, but is eventually scared off by Velma, using a spotlight.

The man thanks the gang and introduces himself as Marius Brancusi, the ringleader. Marius inherited the circus from his uncle last year and has been working to modernize it. He informs the gang that the werewolf they had encountered has been shadowing the circus for a few months, has scared off many of his artists, and has stolen jewelry wherever they are. He even suspects that the werewolf might be one of his own artists. Velma notices that this incident alludes to a case during the 18th century, in Ingolstadt, where a werewolf named Hans collected a combination of jewels which enabled him to change into a werewolf at any time.
