2519 Skeleton Bowling is a 371 piece Ninjago set that was released in January 2011. The set contains a semi-hexagonal structure, with a "life counter" in the center and weapon racks, flags and flick missiles positioned around the outside edge. Positioned around the spinner are six Skeletons, which, when Jay is on the spinner, he can knock down with either his black katana, or one of the many other weapons available in the set.
