Ham 'Em High 13-4

Theme 13-4 is the fourth level of the second theme of Ham 'Em High.

Strategy
Fling the Red bird into the ice leg of the rightmost tower. There can be an extreme amount of secondary destruction. In some cases, only one or two pigs remained. Luckily, in most cases, any remaining structures should be quite weak and the Blue birds should finish the level nicely if there are some remaining pigs.
