Ceramic Ninja Mug (CNM) is a silent assassin who lurks around casually at home or in your office cubicle until you start feeling sleepy. Then CNM goes into action, with the black mask on to keep your drink hot for longer periods and also cover up his real identity as an ordinary ceramic mug. There’s no escape for a snooze when the Ninja Mug slashes his weapon of choice – a wooden spoon sword. Once CNM has forced the caffeine down your gullet and killed your urge to doze off, he disappears without a trace with the help of a sidekick named Ceramic Shuriken Coaster (CSC) who makes sure there are no tell-tale signs of the coffee-break adventure left behind on the table or your desk.
