Slice store-bought chocolate cake into a coffin shape. Insert a skewer near top of coffin. Place a mini marshmallow onto skewer, and then add a pretzel twist. Then add two more pretzel twists and mini marshmallows. Use a black food-safe marker to draw a skeleton face on a regular-sized marshmallow and add it to the top of the skewer.
Melt candy melts according to package instructions. Dip pretzel sticks in the melts until coated; set on parchment or wax paper to dry. When dry, stick into the second mini marshmallow as "arms."
Use two pieces of licorice chalk to form a leg, then insert yogurt-covered raisin vertically into cake to form "foot"; repeat to form second leg and foot.
