There are new Ninjago booster packs appearing throughout 2012. Some sets are available early in the year with others appearing during the summer and fall sets appearing in time for Christmas.
The Ninjago booster packs are add-ons for the Spinjitzu game. They are also useful for building up a collection of Ninjago minifigures because they are the cheapest Ninjago sets.
Each booster pack comes with a minifigure with accessories and weapons and also add-ons for the Spinjitzu spinner. The booster packs don't contain spinners so you'll need to have some of the 2012 spinners already.
Some of the new 2012 booster packs contain special weapons that clip on to the bottom of the new 2012 spinners.
Which Ninjago 2012 Booster Pack do you want and why?
