Angry Birds Seasons Piglantis Level 2-8 Walkthrough
One strategy for Piglantis level 2-8 is to send the Blue birds just above the first hollow ice square, clipping the top to do a little damage, and onto the TNT below. You can manage to clear three towers, and perhaps even the pigs in the largest trough. Then use a bird or two to detonate the far-right TNT to finish the level.
