Danger Above 7-9

Theme 7-9 is the 24th level of Danger Above.

Strategy
Fire the Red bird head-on into the hollow stone square, popping the pigs at the extreme left. Loft the Boomerang bird over the structure, spinning it just above the horizontal wooden plank. With a bit of luck, the falling stones can trigger the TNT in the middle of the level, clearing all pigs.
