How to get three stars on angry birds space world 2 level 16
Another one of those levels where you need to not take out the pigs with as few birds as possible. If you do you just wont get enough points to get your three golden stars. What you need to do is make sure you push as much as possible of the debris in front of the pigs into the gravitational pull of the big ice planet. One of the best ways to make sure you do is to shoot the three big green birds as I have marked out in the screenshot above. Also worth noting is that the ice crystals on the planet surface is worth a lot of points if you take them out with birds or debris.
