Moves: 30
This level starts on the first of two screens with a single jellied square right in the middle, your first move should spread that jelly, because your subsequent moves are going to need to start from atop of the jelly.
Tips for screen one:
1. Focus on uncaging the color bomb and the color changer on the right and left of the screen. You'll need to make striped candies and use them in the right places or simply use fish. You can also use stripes with color bombs. Whatever you do, you will need to start from a jellied square so that you can jelly the side squares without detonating the special candies. They will drop on the next screen and probably be more useful there. If you don't uncage them from atop a jellied square, you will need to detonate them from a jellied square to move to the next screen.
2. Fish drop from the upper right corner square and the upper left corner square, usually about 4 of them. You can use a double fish to uncage the color bomb and color changer (only do this if your fish are over jelly), but it is best to save one fish pair to deal with your last 3 unjellied squares, otherwise you will waste many moves that you'll need on the next screen.
3. Make a few special candies but don't use them, you will need them after your jelly has been spread on this screen.
If you seem to have a lot of moves left, and the screen is nearly covered in jelly, don't get too excited, there is a second screen.
Tips for screen 2:
1. Hopefully, you left some special candies, if you left the color bomb and the color changer in their isolated side squares on screen one, they will drop down on this screen after 2 candies underneath them are matched.
2. Don't worry about breaking the lower blocks, or even all of the four blocks in the middle of the screen, they are already jellied underneath the blocks. The only reason to eliminate them after the first one is to give yourself room to make special candies. If you look closely at the image above you can see the jelly poking out from under the frosting blocks.

Note that to save your ego I have also left the video at normal speed with all my slow thinking and screw ups. Feel free to speed up the video in youtube by clicking on the gear, then speed, then 2.
