Bat

Bats are nocturnal creatures that rely on sonar to get around. Bats have fox-like faces and leathery wings.  There are many sizes, shapes, and colors of bats. The vampire bat, which most people think of on Halloween, is a real South American bat. It survives by sucking small amounts of blood from livestock and other animals at night. It has never, drained any creature dry, nor to our knowledge ever attacked a human.
