Select three distinct food colors. In a large pot, melt the butter over low heat. Add the marshmallows and stir them together until they’re fully combined, using a wooden spoon. This process should take about 3-5 minutes. Once the marshmallows are melted and combined, set aside the mixture.

Pour half a cup of the marshmallow mixture into a large bowl. Add one of the food dyes to the bowl and mix it into the marshmallow mixture until it’s well combined.

Add 2 cups of crispy rice cereal to the dyed marshmallow mixture. Use a wooden spoon to mix the cereal and marshmallow mixture together.

Spray the gloves with cooking spray to prevent them from sticking to the crispy rice cereal mixture in the next step. Use gloved hands and form equal-sized crispy rice balls.

Place crispy rice balls on a lined baking sheet and press the sugar eye into them.
