Our strategy for Angry Birds Free Birdday Party (Birthday Party) Cake 4 level 3 is to fire the first Blue bird straight ahead, but high enough to minimize the amount of debris left behind. With the next bird, keep it low enough to break the ice block just left of the central pig. So long as the pig is exposed, it is not necessary for him to pop on this shot. Fire another bird into the right-most structure, and debris should clear all remaining pigs.
