Unroll and remove the plastic backing from the grape flavored fruit leather, and place it shiny side up on a cutting board. Fold in half so that the shiny side sticks to itself creating a double layer of fruit leather. Press a bat cookie cutter into the fruit leather. But rather than trying to muscle the cookie cutter through the top of the fruit, flip over the fruit leather and cookie cutter together. Working from the back side, use your fingertips to push the fruit leather through the cutter to ensure the cuts are clean and go all the way through.
Repeat. 1 fruit roll up makes ~6 bats that can be placed on the center of the moon as a quick and easy garnish for each martini.
Bat picks (optional): To make bat picks, you'll need to make 2 more bats from another fruit rollup to give you a total of 8 bat cutouts. Take two bats and sandwich a toothpick between them using a dab of jam as glue. Repeat with the remaining bats until you get 4 bat picks.
