Desmodus Rotundus abound and one supposes that they become more rotund after they've feasted on you while you sleep. It doesn't hurt until the morning though because they inject a certain anaesthetic into your vein while sucking away. Rabies is epizootic with the cute little fellows so, what with blood loss and hydrophobia you'll probably faint, fall into the long drop, and scream at the sound of it sploshing all at the same time. It's very Roman Polanski!
