I think that Kankuro has 3 dolls now. ( It looks like it on the last page)

and I'm sure that Kimimaro will put up a really good fight vs Lee and Gaara, he can do whatever he wants with his bones, like change to shapes of them, split them, increase the durabillity and stuff like that so I'm sure he will find a way to penetrate Gaara's sand or he will just do something else awsome with lvl 2
