Wreck the Halls level 16 is a bit difficult. Our strategy is to fire the first Blue bird just above the left-most stone blocks, splitting as late as possible. Fire the Orange bird just below the left-most stone blocks and trigger him to expand when he reaches the middle of the structure. With some luck, the only pig remaining should be in the top-right: Use the Blue bird to thread the needle. The score in the video below is 92,790.
