You have what you need to do this in place already, the challenge comes in needing 4 vertical striped candies placed properly to finish this. You need 2 vertical striped candies in the middle column, one to unlock the middle piece and shoot through the locked jelly, and a second to shoot through the jelly again. You also need to unlock the horizontal striped candies in the second and 8th columns. Shooting through one of them will unlock it and shooting through it again will set it off and allow you to clear the jelly horizontally.

Vertically striped candies will get to the locked candies and jellies and release and clear them, but striped/wrapped combos require less precision. They hit a 3 column area and may be easier to make.
