Birdday Party (Birthday Party) level 18-8 is very difficult. Our strategy is to loft the Boomerang bird so that it hits the TNT in the middle of the level directly. Next, loft the Yellow bird is a similar manner, using the speed boost to push the boulders on the far-left into the gap, which was already damaged enough so that all pigs are popped except for those on the right. A well-placed bomb from the White bird just left of the right-most structure will pop the remaining pigs. The score in the video below is 89,790.
