Grind the cookies in a food processor, or smash them in a plastic bag with a spoon or rolling pin. You want to ground them to a fine powder.
Break up three candy corn bars into pieces inside the wrappers.
Add the cookie powder, softened cream cheese, and candy corn bars to a bowl. Mix well.
Roll the dough into 16 balls and place on a plate with wax paper. Set in the refrigerator for an hour.
Warm the candy melts on the stove or microwave according to the package instructions. Dip the truffles into the coating using your tool(s). Place on the wax paper.
Repeat with all of the truffles. Place on a paper plate and let cool.
Put some of the candy coating into a piping bag and close the end. Drizzle lines that look like mummy bandages over the coating.
While the coating is still warm, place the candy eyes and bones on the truffles. Let cool an hour before serving.
