Lob the Boomerang bird over the structure and spin it back through the wooden block on the right side. Ideally, the Boomerang bird should go far enough so as to break the hollow wooden square within. In any event, the whole right side should be cleared with significant damage. Fire a Yellow bird horizontally, through both pieces of wood on the left side. To earn 3 stars, it is important to break the jewel in the trough. Be careful of the encased pig (which is in the hollow wooden square block) that falls leftward, since he doesn’t always pop.
