Theme 15-10 is the tenth level of the first episode of Mine and Dine.
Fire the first Yellow bird through the wooden block (not the hollow square) on the left side. This should cause about half of the structure to collapse. Ideally, the pig in the bottom-left should pop. Launch the next Yellow bird through the wood in the middle of the level. If pigs remain, you have a Yellow bird and Big Brother to clean up.
