Once cupcakes are fully cooled; prepare frosting in a piping bag fitted with small circle tip.
Pipe frosting in a squiggly pattern. Run a line down the middle using a toothpick. (This does not have to look perfect because it will be covered with jam.)
Refrigerate frosted cupcakes for another 15-20 minutes.
Let jam sit at room temperature while frosting is cooling.
Gently coat frosting with strawberry jam, using small silicone pastry brush.
Paper feathers should be glued to lolipop sticks.
Printable zombie liners can be attached to empty black cupcake liners with tape or glue.
Insert arrows into cupcakes once glue is completely dried.
Place cupcakes inside the zombie cupcake liners.
