This video shows you one way to achieve 100% Total Destruction on Angry Birds Surf and Turf level 11. If you have an alternate strategy please feel free to leave a detailed comment below.
Send the first Blue bird through the left side of the structure. Fire the White bird downward, bombing the thin ice blocks and ricocheting the bird into the top of the tower. Use the Yellow and White birds to clean up the left side, then place the Sardine Can next to the TNT block.
