Lego Ninjago: Warriors of Stone Volume 6

Jay, Cole, Zane, Kai and Sensei Wu are strangers in an even stranger land - Garmadon City! But the name is not what's strange! The fact that everything is made of stone - the streets, the buildings, the trees, even the people! - that's the really strange part. But how do you save people who have been turned into stone who don't want to be saved, and will do anything to stop you? That's what the Masters of Spinjitzu must find out before it's too late!
