'Tis the night before Christmas and there's trouble at the North Pole. Jingle, a frustrated elf, has taken one too many perceived slights from the Big Boss. So, he puts an evil spell on Santa's Cache of Ninja teddy bears. The nunchuck-wielding plushies spring to life, terrorizing Santa's workshop and threatening the celebration of Christmas! Who will save the day? Why, Santa, of course, morphing from jolly St. Nick to his butt-kicking alter ego, Manga Claus!
