Yet another Ninjago set in our household. This one has 418 pieces which you use to build a battle arena, snake and dragon attack models, 2 spinners and figures (incl. 5 trading cards for each) and 9 weapons. Basically it's just another battle arena but it takes a lot longer to build as you have to build the snake and dragon. They look quite exciting as they launch their heads forward to knock the figures down but they don't really reach that far. They do slow the figures down which my son says makes it less interesting. He mostly seems to play with the snake and dragon models which he has taken off the arena so they can fight each other!
