One strategy for Angry Birds Facebook Pig Tales level 15 is fling Red bird directly into the first tower. It should collapse to the right and clear most of the pigs with the help of the Fairy bubbles. Finally, drop an egg bomb on any remaining pigs.
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.
