There are a lot of variables to keep track of in this level, but before you can really begin working on your main objective, you have to blast through the three-layered icing. Since each icing has so many layers, you will want to make moves that hit multiple icing squares at once.
This will allow candies to reach the bottom of the board faster. It is required to do this before the first moon struck occurs.
The most efficient way to get rid of obstacles is, of course, by using special candies in combination with one another. Unfortunately, the colour bomb will probably not be available to you for quite a while.
The striped and wrapped combination is one of the most useful possible combinations in this level. Not only will it get rid of icing, it will also destroy liquorice locks and the free the candy bombs to destroy. Other special candies trapped in marmalade could also be released. You can use these more combinations later in the level.
Odus is going to be precariously balanced all through this level. There is not much you can do about it except to fill up his meter. Make a few matches to keep the owl balanced in the meantime. Odus will remove two colours of candy from the board during moon struck. This includes any matching candy bombs, so prioritize removing bombs that do not correspond to either colour if necessary. You need to rely on a good moon struck to complete this level.
