Monster High is facing a series of bad luck incidents, since "Friday the 13th" and "October 31st" strangely coincided this year. Deuce Gorgon encounters a black cat, and then has his own powers turned against him by a mirror. He is left petrified. Lagoona Blue informs her friends that the bad luck will last until 3 PM, meaning that they will have to endure 6 hours of misfortune. Cleo De Nile informs her friends that she brought a protective amulet with her. It is supposed to protect its wearer and the wearer's companions. Frankie asks about the location of the amulet, and Cleo says that Ghoulia Yelps is carrying it for her. At that moment, Cleo and her friends realize that Ghoulia is not standing beside them. The girls can see Ghoulia walking alone in the distance, and try to catch up with her. Rain and storm start inside the school, and the girls are struck by lightning. As they observe Ghoulia, they see the zombie girl tampering with the school's clock. Ghoulia moves the clock's hands forward to 3 PM, ending the bad luck wave prematurely. The girls starts conversing on whether the amulet fits with Cleo's outfit.
