Our strategy for Angry Birds Facebook Surf and Turf level 21 is to fling the yellow bird up at a high arch towards the far right tower with the goal of breaking the wood beam supporting it. This will cause the debris to fall into the chasm, detonating the TNT and popping the pig. Now finish things off by firing the blue bird straight ahead at the glass, taking down the tower and popping the remaining pigs. The score in the video below is 90,350.
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.
