Vampire bats, certainly
When Vampire Bats leave a cave they fly in a left-spiraling pattern to keep from bumping into the others.
You can become a vampire if you meet one and become friends until it bites you, but to fly like a bat you click a spot (as a vampire) and choose 'fly here'
the only animal a vampire can turn into is a bat you click on a spot choose "fly here" they turn into a bat fly to the area you tell it to go then will turn back to a normal vampire
