You have a U shaped row of single jelly, and then 5 hit blocks with jelly under them. Then, to top if all off you have a single piece of jelly in the bottom left, center, and right side of the board which are almost impossible to get to if you don’t use the jellyfish provided. Clear out all the jelly on the board before using it otherwise you will never pass this level. You can mix the jellyfish with striped candies for added effectiveness if you still have other jelly around. You are going to get a LOT of 10 move bombs, so you have to keep tabs on them as well as trying to make your way through it.

A color bomb/striped candy combo will really help with the blocks and clear the jellies. A second color bomb matched with a same colored candy as in the isolated jellies can remove those.
