Ahhh, this one stars my favorite Destructive Duo, Bubbles and Bomb, AKA OB&BB. We only need two sow the seeds of destruction and reap a score of 135430. Check out the video below.
Send OB in a medium arc to penetrate deep into the upper structure. His expansion scatters wood, stone, and pigs alike. Next, BB goes low blasting it to bits and turning the remaining pigs into piggie poofs. Another OB&BB hang out by the sling and collect another 20K.
