The pierces are a really great idea. They're basically like the TamaGo's figurines done properly. If you own a P's, I'd definitely recommend these.They add a whole new level of replay value as well as content, and on top of that, they're a cute way to jazz up your Tama. I keep my Royal pierce in even when I don't need to use it because it goes really well with the white and it just looks nice. Since the Circus and Royal pierces, four new ones have been released.
