This one's easy to miss, but Hanks also voices the Ebenezer Scrooge puppet, which the man on top of the train uses to scare Hero Boy into doubting that the Polar Express is real. "You are just like me, my friend: a scrooge!" the puppet says, frightening the Hero Boy. "North Pole, Santa Claus, this train — it's all a bunch o' humbug!" The Hero Boy does eventually notice that it's just the man on the train playing a trick on him, but we don't blame him for scurrying away anyway after hearing Hanks's booming voice reverberate through the moving train car.
