Cosmic Crystals 7-29 is the twenty-ninth level in Cosmic Crystals.The objective of level 7-29 is to use the birds to eliminate all the pigs. Get at least 110,000 points for 3 stars.
This level is a bit tricky, but you have five birds to clear. However three stars score is quite high.
Send the Orange Bird near the cluster of asteroids on the west side of the level. Then send the Black Bird just barely grazing the gravitational field of the southern planet and blast the weird space contraption to bits. The debris should be forceful enough to break the remaining planets and pigs. If necessary, use another bird to clear the remaining ones.
