Have ready a place to stand up the apples once they are on the sticks and dipped, such as a sturdy block of Styrofoam or a shallow, sturdy cardboard box with holes punched in the lid.
Have the candy eyes opened and in a small dish.
Stick the wooden sticks into the bottom of each apple, leaving enough stick out to use as a handle.
Melt the candy melts:
Pour the Candy Melts in a medium heat-proof bowl (use separate bowls if you're using more than one color.)
Microwave the Candy Melts in 30 second bursts, stirring each time, until the candy is completely melted and smooth. (It will be a little thick. Do not overheat it.)
Coat the apples:
Holding the apple by the stick, roll it through the melted Candy Melts until the top and sides are coated. Tap off the excess or use a small rubber spatula to smooth off the excess.
While the coating is still wet, press candy eyeballs all over the apple. (Add in 1 or 2 larger eyeballs if you're using them.)
Stand the finished apple up in the prepared Styrofoam block or the box.
Continue to dip and decorate the remaining apples. Allow them to dry completely - this should only take 10-15 minutes.
When the apples are all dry you can serve them immediately. or gently wrap them in plastic wrap.
Store them at room temperature for up to two days.
Notes
Look for Candy Melts and candy eyeballs at stores that sell candy-making and cake-decorating supplies, or order them online.
The Candy Melts melt easily - just be sure not to overheat them, as they seize when the temperature gets too high.
