This video shows you one way to achieve 100% Total Destruction on Angry Birds Surf and Turf level 6. If you have an alternate strategy please feel free to leave a detailed comment below.
Fire the first Yellow bird through the wooden plank supporting the boulders. Use a Blue bird to clear as much ice from the left side as possible. Launch the next Yellow bird into the main structure and use a Blue bird to clean up the fallen debris. Place the Sardine Can on the left side of the central platform.
Took 3 MEs
1. Yellow Bird straight into the wood to the left of the left most pig.
2. Blue Bird in the glass on the ground breaking near the sling and then moving to the right.
3. Sardine Car into the base of the green rock that is under the left most pigs.
All three stones need to roll down the hill and take out the wood.
Also if luck is with you, it helps when the ME hits the Yellow Bird.
