Our strategy for Mine and Dine level 15-5 is to launch the White bird towards the middle structure, bombing the stone blocks on its left, and ricocheting the bird into the suspended pigs, popping at least two of them. Fire the next White bird a little lower, bombing the rest of the stones and clearing the left side of the level. Launch the Yellow bird directly into the TNT on the right side, and use the Red bird if necessary, to finish the level. The score in the video below is 114,320.

1. White Bird drops egg on left structure and shell takes out the 3 stalactites. Most of the left structure is gone.
2. White Bird drops egg of left side of middle structure and the shell activates the stones above buy destroying the pig and wood supports below. The whole pile of stones fall onto the structure below. The goal is to obtain a good debris fall with a good deal of destruction so the debris pile is small.
