To a large mixing bowl, add the rice cereal, kettle corn, and mini pretzels. Mix well.
Add the white chocolate chips to a heat proof bowl, and microwave in 1 minute increments, stirring in between, until smooth and glossy.
Pour the melted chocolate into the bowl, and mix well to coat all the ingredients evenly. Then pour the snack mix onto the prepared baking sheet, spreading it out into one even layer.
Sprinkle over the candy corn, M&Ms, candy pumpkins, candy eyes, and sprinkles.
Cool for 30 minutes or until completely set. Then break up into pieces before serving.
