A draw to adopt from

Aroo-Aught is nary three feet tall, but don't let his appearance fool you. He's a killer. Without hesitation, he will kill people and they don't often see it because of his cute face. But by the time they notice that it's too late. He doesn't kill for food. He doesn't even kill for sport. He simply kills because he enjoys killing and he's considered a menace by the few who have heard of him.
