Level 2305 is the fifth level in Sugary Stage and the 908th jelly level. To pass this level, you must clear 38 single and 17 double jelly squares in 17 moves or fewer.
When you complete the level, Sugar Crush is activated and will score you additional points.
Destroy as many jellies as possible on the top part of the board before going after the jelly fish. Also, a colour bomb + colour bomb combination will get you an instant win because the combination will destroy most of the jellies and simultaneously activate the jelly fish which will destroy the rest.
