I throw a ninja star at your face while being ninja, you not knowing where I am, then I slash my katana (Or sword) at light speed, cutting you up like minced meat. I collect them like a master sushi chef and dump you to the piranhas to be eaten. I snatch the cookie while you are eaten.
As you are running, I stick out an iron bar and you run into it with your head. While you are unconscious, I take the cookie and hide in my secret underground bunker.
