Begin by popping enough popcorn to fill 16 cups, ensuring to remove any unpopped kernels. Place the popped popcorn into a large mixing bowl and set it aside.

In a large pot, add 10 ounces of mini marshmallows and ¼ cup of butter, then heat over medium heat, stirring constantly for 5-7 minutes until smooth and fully melted. Pour this mixture over the popcorn.

Gently stir the melted marshmallow mixture into the popcorn, ensuring every piece is well-coated.

Lightly butter your hands and shape the mixture into golf ball-sized balls, placing each on a lined baking sheet.

Allow the shaped popcorn balls to cool and set for 30 minutes to an hour at room temperature.

Melt the bag of Wilton bright white candy melts according to package instructions until smooth.

Dip the tops of each popcorn ball into the melted candy, allowing excess to drip off. Return to the lined baking sheet and add candy eyeballs while still wet.

Let the candy coating set completely before serving, which should take about 20-30 minutes.
