Zombies in the Snow was a movie directed by Gustav Sebald. The movie appeared in The Reptile Room, when Dr. Montgomery, the Baudelaires and Stephano went to see it. It's revealed to contain Sebald Code, but Dr. Montgomery never learned it. The coded message was: 'Attention! Hidden in the snowman is a survivor of the fire. Meet us in the town where this film takes place. Bring the three children. Your new assistant is not one of us. Beware!'
