1. First bird (bomb) with KS must roll down and destroy most of the center.
2. SS-Second bird (boomerang) and squash from the top the rigth structure (do not activate boomerang;the weight will do)
3. Third bird should do a high-arc and go all the way down to the rock triangle.
The aiming of the three shots is quite tricky and is better done by going all the way down the screen (where everythign is black). It sounds silly, but some post-it arrow flags can work wonders for this… just saying…
