Unwrap your rice kripsy treats, or cut your completely cooled rice krispy treats into small rectangles.
In a small microwaveable bow, add your melting chocolates and microwave for one minute. Stir after the one minute cook time to help them melt. Cook for an additional thirty second and then stir again until smooth. Cook for additional 30 second bursts, stirring after, for as long as needed. See notes below.
Dip the top half of your Monster Rice Krispie Treats into the melting chocolate covering the front, back, top, and sides. Don't over-coat.
Lay the treats flat onto the wax paper, and gently press on the eyeball candies.
Let the treats cool for 30-60 minutes to make sure the chocolate cooled completely.
Notes
Don't overcook the chocolate or it will seize up and become unusable. A minute and a half should be sufficient cooking time, unless you're cooking a whole bag at once.
Michael's sells a wide range of colors in melting chocolates, but you can also get them at Hobby Lobby and Walmart.
