Theme 16-6 is the sixth level of the second episode of Mine and Dine.
Fire the first Black bird into the jutting ice block of the second tower. When the bird is just above the lowest triangle of the last tower, trigger the detonation. Most of the right tower should fall, the middle tower should topple to the left, and a fair amount of the left tower will be destroyed as well. Use the next Black bird wherever the most stone is. In the video, only one pig at the right remains, so it is used there. If there are pigs in the middle, it is better suited to be lobbed into the center.
