Pop your popcorn in an air popper, or a pan until all the kernels are popped. Put in a large bowl.
Sprinkle popcorn all over with salt.
In a large pan over medium high heat, melt your butter. Add in your vanilla and marshmallows.
Stir constantly till the marshmallows are melted and creamy.
Pour the marshmallow mixture over your popcorn and stir until popcorn is fully coated.
Allow to set for a couple minutes, then stir in half of your reeses pieces and candy corn.
Separate your popcorn into 10 sections
Press in the white chocolate pretzels (they'll melt if they go in sooner) into each section.
Shape popcorn into balls. If the mixture is sticking to your hands, spray them with nonstick spray as needed.
Press additional candies onto the outside of the popcorn balls.
Place balls on parchment paper and allow to set for about an hour.
