a medium mixing bowl, add the food coloring to the potatoes a few drops at
a time, stirring to combine. Add more coloring to achieve the desired
shade of purple.
2 tablespoons of the potatoes onto the center of each of 4 microwave-safe
plates. With clean, damp fingers, shape each scoop of potatoes into a
vertical rectangle about 1 1/2 X 3 1/2-inches, forming the bodies of the
bats. Spoon remaining potatoes into a plastic, zip-top sandwich bag; press
out the air and zip it closed. Snip one-half inch off of one corner at the
bottom of the bag.
the potatoes out of the hole in the bag, pipe a 5-inch wide, shallow,
inverted "V" on each side of the rectangle bat body to form the
top of the bat's wings. Then pipe a wide "W" to form the
underside of the wings. Squeeze some potatoes in the center of the wing
and spread with a small spatula to fill them in.
create ears on the top of the body with two corn kernels; use a small
piece of red pimiento for the bat's mouth. Repeat with the remaining
potatoes on three additional plates to make a total of four bats. Reheat
the bats in the microwave and serve.
