Preheat the oven to 255°F (124°C). Combine the Bugles, cheese crackers, popcorn, and pretzel sticks in a large roasting pan.
Bring the brown sugar, corn syrup, butter, and salt to a boil in a medium saucepan over medium heat. Cook for 5 minutes, stirring frequently.
Remove from the heat and stir in the vanilla and baking soda.
Pour the syrup over the snack mixture and stir gently to coat.
Bake for 1 hour, stirring every 15 minutes.
Spread the baked mix on waxed paper in a single layer and cool completely.
Microwave the candy coating for 1 minute. Stir until smooth, then attach candy eyeballs to the Bugles with small dots of coating.
Transfer the cooled mix to a large bowl. Stir in the candy corn and Reese’s Pieces.
