Hi Y'all! As you may know (or not) I'm a fan of the BBC Series Doctor Who. Special characters are the Weeping Angels
(They're a race of predatory creatures. They are as old (or almost as old) as the universe. However, no one knows where they come from. They turn into stone when they are viewed. In this form, they usually hold their hands up to their face to avoid that they see each other and they must remain in the locked form forever. From this attitude they get their name Weeping Angels. When no one is looking the angels move very quickly. They use this capability for stalking and also to attack and kill unwary prey.)
For those of you who want to know more about the weeping angels, can read about them here and here.
