Melt butter in a large pot over low heat.
Add marshmallows and stir until melted.
Add crispy cereal and stir until all mixed and well coated with the melted marshmallow.
Pour crispy mixture into a 13x9x2 inch pan coated with cooking spray and press down evenly using some unbleached parchment paper or wax paper.
Let cool then cut into squares.
Place each color chocolate into a small bowl with 1 tsp coconut oil and melt using the microwave or on the stove-top with a double boiler. Mix well.
Dip each crispy treat into the various colors and add candy eyeballs.
Place into the fridge until chocolate hardens.
Enjoy!
