I've been trying to get 3 stars on level 20 for a while and I can't figure it out. I get more points if I send the bird flying directly through the pigs instead of just bursting their bubble things but it's not enough. The grass stuff on the moon isn't enough points to justify using another bird to destroy it. Can anyone help me with this?

These levels are under Eggsteroids. From the screen containing all the planets, if you scroll over to the 4th planet, you'll see the Eggsteroids levels. Clicking on the planet will show you any unlocked levels and allow you to replay that level. These appear to be comparable to the Golden Egg levels of the earlier games.
If you can hit the 3rd vertical board at the top at the right spot (screenshot below), it will cause enough force to cause the cement block to drop on the first pig, and the ice block to hit the 2nd pig, which will then push things enough to knock over the tower with the 3rd pig.
I did this 3 times and averaged about 48,000 on each attempt which was enough for 3 stars on the iOS version.

I've been retrying this level now for a few times just to check. Using just one bird, it gave me 2 stars once and 3 stars all the other times. That was apparently unrelated to me bursting their bubbles as opposed to hitting them directly, and independent of me shaving some grass. So I guess there's just some fluke - I recommend you just try it a few more times.
As a way of adding variety to your tries, try shooting into them a different direction than the one you've been trying - you can shoot into them from below as well as above. It makes shaving the grass or colliding with the moon easier.
