It's the holiday season and, in celebration, West Coast Hall is having its annual party! The girls are amped as everyone exchanges posh gifts (designer silk scarves; overpriced pens; and the newest in micro cappuccino machines) with their Secret Santa -everyone except Clover, that is. When she opens her present and sees that it's nothing but a lump of coal, she quickly realizes that Mandy is responsible! "Happy Holidays, loser!" But before she can protest, Jerry WOOHPs the girls via a holiday hors d'oeuvre platter. Covered in food, the girls receive their mission: to investigate an Unidentified Flying Object hovering above Beverly Hills. When the girls arrive on the scene in a WOOHP chopper, they are relieved to see nothing more than a harmless weather balloon -harmless, that is, until they get too close and it begins firing on them! After an impressive mid-air battle, the balloon and its pilot escape -leaving the confused girls no choice but to return home. When they get back to campus, however, they are shocked to see that it is actually snowing -a phenomenon that has never occurred in that area! As they walk across Mali-U they watch in disbelief as surfers snowboard, rollerbladers ski, and the designer scarves are used as more than just fashion accessories. At first, everyone is enjoying the bizarre weather sitch, but, as it begins to snow harder and harder, things quickly get out of hand. Before anyone knows what's hit them, all of Beverly Hills is buried in snow! Retreating to their penthouse, which is the only place still above snow-level, Sam, Clover, Alex and Jerry investigate (and thanks to a clue they found earlier), the Spies realize that a former and very bitter mall Santa, devised a device capable of dropping an endless flurry of snow on the materialistic people of Beverly Hills -- literally freezing their assets. In a b-story, the girls learn that the holidays aren't about materialism.
