Babushkas are aliens from Neptune, they reproduce by sucking all intelligence out of humans. In -1920 they landed with their vessels in South Carolina looking for intelligence. Since the offer was quite scarce they migrated towards the Bering strait. After many years they reached Russia and Eastern Europe and called it their home. They try to blend in with the humans, but you can still recognize a Babushka if you look at their skin. The skin is formed from the remains of the skin of their victims. Also they always wear a bandana on their head. Biologists still don't know what it's for, but recent theorys say that in their head they have a transmitter that can send all the intelligence they gather back to their home planet.
