A bunch of evil (but equally minuscule) samurai have turned up and started converting all the furry woodland creatures into their own nasty henchmen. Eventually, the master ninja gets wind of this nefarious scheme, and sends his best apprentices down to the cursed land to try to regain some order. Unfortunately, nobody comes back and, out of options, the master sends his last two novices into the fray, in a last-ditch attempt to save the world."
