Mighty Hoax level 4-14 is difficult since your aim is constantly changing. The best strategy is to fire the first Yellow bird through the first three wooden blocks at the bottom of the level. Fire the first Blue bird head-on into the left side of the ice structure. Keeping the next Yellow bird low, pop the three remaining pigs in the lower part of the level. Another shot up high with the Blue bird, and the level is yours. The score in the video below is 89,870.
