Poached Eggs 1-20

Theme 1-20 (AKA:BOULDER BIGHOUSE) is the 20th level of Poached Eggs.
 * Level 9-6 was a copy of this level.

3-Star Strategy
Shoot the first bird into the air, then aim it so it hits the wood between the first couple of stone blocks and the boulder. If one bird wasn't enough to get through, fire a second bird at the same spot if possible, so the strucutre crashes down and kills the two pigs.
