To clear all the jelly here, you have a + shaped double jelly pattern in the middle of the board and double jelly in all 4 corners of the board with 5 hit blocks surrounding the outer border. You are also given 3 jellyfish frozen to assist you in the harder corner pieces. Try to remove the middle jelly and work on the top left and top right areas to try to get to that jelly without using the fish.

Clear the easy jellies first and use the fish to get to the outer corner jellies. Striped/wrapped combos can help with the remaining layer of jellies the fish don’t get to. (Even just exploding a wrapped candy next to the bottom corners can work for that.)
