You have 9 color changing pieces in a + shape in the middle, try your best to use them when they are yellow if that is one of the colors they turn to help you get to your 111 total of yellow pieces. There are 4 chocolate fans in the corners but all are blocked in by locked in mystery eggs. Once the eggs are unlocked use them or move them down or they will probably be devoured by the chocolate fans unless it is a blocker, then definitely leave it! You should be able to get a good bit of striped candies and maybe a color bomb or two to help clean up the board. This level isn’t as hard as it looks as long as you can manage the chocolate.

Try to keep the locked candies in the corners locked to block the chocolate. Since you need to collect yellows, the best strategy is to keep clearing the board—striped/wrapped combos—just steer clear of the corners as much as possible.
