In a large bowl, mix the cream cheese so it becomes smooth and pliable. Add the pumpkin purée, cranberry sauce, pineapple, eggs, egg yolk, sour cream, sugar, cinnamon, flour, vanilla extract and mix thoroughly until smooth.
Pour mixture into the 2 pre made graham cracker crusts and smooth. Put the pies into the oven and bake for an hour. Take out and let cool for 15 minutes. Place into refrigerator and let cool for at least 4 hours.
