Ninja Mug

Don't you hate when you set down a cup of coffee somewhere and lose it? If you were using this cool new Ninja Mug, it probably vanished on its own. This mysterious ceramic coffee mug of death shrouds itself in darkness using a removable insulating sleeve, is armed with a katana sword spoon, and lies in wait upon a deadly shuriken coaster. Hmm, when not in use, it's probably best to keep this mug far, far away from other mugs in the cabinet, unless you enjoy sweeping up shredded ceramic.
