Here is our Mighty Eagle Total Destruction video walkthrough for Angry Birds Bad Piggies level 21-7. (If you’re looking for the 3-star walkthrough video, click here.)
Bomb in the third gap with the first White bird, and in the first gap with the next. Use the next two White birds to clean up debris on the left side. Toss the sardine can onto the sandbags at the extreme right to finish the level. If you have an alternate strategy please feel free to leave a detailed comment below.
Launch the Sardine Can into the helmeted pig with the goggles and it does a slow fall to the left.
