Sand Weasel
A vicious land predator characterized by it's inability to feel sympathy. It has a cute, fuzzy exterior and the ability to kill anything at any time in any place; seriously...it assassinated Abraham Lincoln...John Wilkes Booth just owned one. They are found naturally in large populated areas, where crime lords will pay them to assassinate ANYONE and EVERYONE. The German Poet, Alphred Von Schleeden Ho once refered to sand weasels as "The Sand Veazel" or "Little Satan." In Arabic: "Plague of the Ages."
There was no meteor to kill the dinosaurs, there was only a pissed off sand weasel.
