Koala Tattoo?

Ok I recently go a tattoo on my back, its great and I love it, and now I'm getting another. But I can't find ANY images like it. A Koala, but not a normal one. Like an evil, monster, killer one. Like they do with all sorts of animals, an evil cartoonish version. Has anyone seen any? I've searched everywhere. It would have sentimental value as a koala.....but koalas are kind of puny so I wanted something a little different.
