Ninjas are always sneaking around in their sleek black outfits, karate chopping targets and wagging their freakishly long tongues around? BK Japan's new Kuro Ninja or "black ninja" burger banks pretty hard on that odd ninja concept with a big old bacon "tongue".

The Kuro Ninja features a black bun, which, like the inaugural Kuro Burger, gets its color from bamboo charcoal.

You also get "wide-size" hash browns, onions, lettuce, mayo, and a Chaliapin sauce on this deal!
