Goal: clear all the jelly and reach 12,000 points to complete the level.
Tips: make lots of special candies and combos and hit the cream/icing, the jellies and the fish buoys. Once there can matches to be made in the jelly section, make them, to remove them. Or you can hit the fish buoys for the fishes to eat away the jellies. Note that there are transporters here so the candies can be moved from bottom to top. See how this level is done in video below. Good luck.
