Be sure that you don't overheat and burn the candy melts, or you'll have to throw out the entire batch and start over.
Once the candy melts are smooth, you can dip the Oreos into the melted chocolate and then set them on parchment lined baking sheets.
Add the decorations on top of the colored Oreos. Add eyes to the yellow to make the duck, and then add an orange M&M for the beak.
Once the white Oreos you can add a pattern to make flowers, or a slice of marshmallow with pink dots and a pink M&M to make cute bunny feet.
