13-15 4 Birds
Aim first red bird just above hollow wood square in front of boat. Try to get good penetration to paddlewheel.
Arc second green bird and boomerang to get some pigs and fallout in back of boat.
Aim third red bird to bounce of ground floor in middle-to-front of boat. This is the key shot for a high score. On rare occasions it will bounce off floor and clear a path all the way to back of boat.
Aim fourth yellow bird to get any remaining pigs in back of boat.
(This level can probably be done with just the first three birds)
