I haven't purchased the Mighty Eagle but am curious if it's possible to throw the sardine tin in a spot in which the Mighty Eagle will not achieve completion of a board? Or does the sheer force of the eagle hitting inside or outside the game-play area always cause all pigs to be destroyed? I noticed the ground bounces.
Videos, which are my only source of information at this point, show how the Mighty Eagle destroys mostly everything on the first use but sometimes with a bit of structural integrity left behind, like some bits and pieces on the ground.
I expect the answer to this question will be short. :)
