South Hamerica 1-15

 is the fifteenth level of South Hamerica.

Strategy
Sling Terence at a steep angle to the stone triangle block at the top leftmost tower. If you're lucky, he will make the top leftmost tower falls to the left and then the stone structure at the right will fall and pop the pigs at the right and make the tower falls to the left and destroy the remaining ones at the left. If not, use Chuck to pop the remaining pigs by slinging him to the remaining pigs' positions.
