Preheat oven to 250 degrees. In a roasting pan, combine cereal, pretzels, crackers, and peanuts. In a small bowl, mix together melted butter, Worcestershire sauce, Old Bay, lemon juice, and hot-pepper sauce. Pour butter mixture over cereal mixture and stir until ingredients are completely coated. Bake 1 hour, stirring every 15 minutes. Transfer mixture to two rimmed baking sheets to cool completely.
