One bird. Just kept flinging, splitting low over diagonal glass. Did manage to blow TNT, A fair amount of debris left on left side.

Followed @comex666 video. Worked perfectly.

3 birds. Nothing special with strategy. First bird cleared entire left side. Second bird cleared right side. Might have had 3 snowballs left. Third bird pounded left side of ice and cleared most of it.

One bird. Dropped bomb in between first and second tower. Ricochet through to the boulders and all fell to the left.
