Here is our Mighty Eagle Total Destruction video walkthrough for Angry Birds Bad Piggies level 21-3. (If you’re looking for the 3-star walkthrough video, click here.)
This may be the hardest feather so far in Bad Piggies. Use three Black birds on the left half of the level. Fire the Blue bird through the top gap to cause stones to fall inward, onto the wooden bridge. Fling the sardine can onto the ground in front of the slingshot and hope the Eagle destroys (nearly) all of the stone. If you have an alternate strategy please feel free to leave a detailed comment below.
