One strategy for Angry Birds Facebook Pig Tales level 12 is send Bomb bird directly into the first tower and detonate upon impact. The explosion should send debris and the fairy bubbles to the right, destroying most of the pigs. Finally, use the White bird to drop an egg bomb on any remaining pig.
Our Angry Birds Facebook walkthroughs show you how to obtain 3 stars, most of the time without the aid of Power-Ups (we do make exceptions). If you have a different strategy feel free to leave a comment below; however, don't just post your score via the comments, as that's what the Facebook leaderboard is for.
