Poached Eggs level 2-12 is quite challenging. Our strategy is to fire the two Blue birds relatively flat, taking out as many of the ice blocks as possible. Make sure all of the birds have disappeared before moving onward. Then loft the Yellow bird through the wooden planks and vertical support within the structure. The stone blocks should cave inward and pop the remaining pig. The score in the video below is 62,440.
Note: The last vertical plank in the video below is wood. On some platforms, and in older versions of the app, the plank is stone.
