Our strategy for Mine and Dine level 15-12 is to loft the White bird to bomb the middle tower, causing the bird to ricochet into the stalactite above and one of the ropes holding the suspended pig. Fire the Boomerang bird to a direct hit on the far-right tower. Lob the Black bird to land between the first and second roof, just left of the TNT. Use the next two Yellow birds as necessary to finish the level. The score in the video below is 119,880.
