Lay the s’mores on a parchment paper-lined (or wax paper) cookie sheet so there is an equal amount of space in between each s’more.
Working with one color at a time, melt the Candy Melts based on the package instructions.
Spoon the melted candy over half of a s’more (diagonally). Then quickly top it with candy sprinkles and graveyard candy decorations (candy bones, tombstones, bats and/or eyeballs) before the candy coating sets. Repeat the process with the remaining s’mores.
Put the cookie sheet in the refrigerator and let the s'mores chill for 20 minutes or until the candy coating is set and can easily pull away from the parchment paper.
Just before serving, slightly warm each s’more in the microwave just enough so that the candy coating is soft and starts to melt (try 6 seconds at a time; not more than approximately 12 seconds in total).
