This video shows you one way to achieve 100% Total Destruction on Angry Birds Surf and Turf level 3. If you have an alternate strategy please feel free to leave a detailed comment below.
Use the first Yellow bird to take out the support of the left structure. Use the next bird to clean up all resulting debris. Then knock over the right tower with the next two birds, acting quickly. Loft the Sardine Can to land on the small ice blocks in the bottom-right.
Pretty much followed the video. There was one tiny piece of wood left on the sand to the left of the structure, which wasn’t destroyed by ME. Took 3 MEs; not doing too well even with walkthroughs.
Basically the same strategy as the video but used one less Yellow Bird. After the third bird is launched going over the top of the stone structure to destroy the right side, launch the sardine right behind the YB to get into the remaining structure on the right.
