Pour Rice Chex in a large bowl.
In a smaller bowl add your chocolate chips and melt in microwave (stirring occasionally to prevent burning).
Pour over your Rice Chex and stir until totally coated. Add your caramel sauce and stir again until it is also coating the cereal. Add powdered sugar and stir (or put a lid on the bowl and shake) until all the cereal is evenly covered.
Add candy corn, pumpkins, and Sixlets.
