Danger Above 6-8

Theme 6-8 is the eighth level of Danger Above.

Strategy
Fire the first Black bird into the top of the first tower, clearing the two pigs there. Aiming a little higher, place the next Black bird into the base of the tallest tower, demolishing it. Use the two remaining birds to clean up as needed. If the White bird is necessary, you can likely accrue more than 10,000 points in damage with the Black bird.
