Bad Piggies 21-15

Bad Piggies 21-15 is the 15th level and the last of the full 21st section of Bad Piggies in Angry Birds.

Strategy
Fire the first Yellow Bird at a very high arch so he comes down in the leftmost gap. Speed burst and split the long middle wood beam below the helmet pig. With a little luck, this should take down the tower and pop most of the pigs. Fling the white bird over towards the stone tower, detonating at the last second to blow it to smithereens. If necessary, use the last two birds to pop the remaining pigs while destroying as much debris as possible.
