A one-bird strategy for Angry Birds Surf and Turf level 33 is to send the Red bird straight ahead to the first boulder. It should roll to the right destroying most of the lower structure. With a little bit of luck, debris will also destroy the wooden blocks supporting the top left pigs. Use the second bird to topple the column supporting the last boulder to finish off the last pig. The score in the video below is 92,360, without toppling the crane on the right side.
