Our strategy for Summer Pignic level 25 is very nice one-bird clear. Lob the first Yellow bird nearly straight up, triggering the speed boost so the bird is traveling slightly upward through the two thin vertical wooden blocks. With some luck, the Yellow bird can pass through the entire left structure and drop to the TNT below. The tower of the left structure tips to the right and takes out the remaining pig. If this fortune does not happen for you, snipe the pig with the next Yellow bird. The score in the video below is 105,180.
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 leaderboards are for.
Yellow bird takes out the bottom hollow wooden square in the first tower.
Red bird takes out the bottom left wooden ‘leg’ of the far right tower without hitting anything else causing that tower to fall left.
Boom ….. 121,820 …… two birds.
If you still have your old phone, I think there is something to salvage. Check out the forum and sift around. There are some (non-Rovio official) AB Android transfer apps in there listed. There also may be some listed in the comments on the iOS transfer page.
