Goal: clear all the jelly and reach 28,000 points to complete the level.
Tips: make lots of special candies and unlock, unmask the candies and remove the jellies while hitting the magic mixers. They must be removed as quickly as possible. Otherwise, you will need to keep the very short-timed bombs in check while still removing jellies. Not fun, not easy. See how this level is done in video below. Good luck.
