Theme 5-2 is the second level of Theme 5, the 23rd level of Mighty Hoax, and the 86th level in Angry Birds overall.
3 Star Strategy
First, send the Blue Birds high aiming for the middle tower. You have to split while they're still in the air, so the three triplets land in nearly the same spot. If you have the stone block land on the first Helmet Pig, it will clear the whole level. The unused Red Bird and Yellow Bird will award the player an extra 20,000 points.
