The attached screenshot is just before trying to clear the last sprinkle. The problem here is that the fish don't target the correct candy. They keep swimming to the top and clearing things that don't matter. It should be going to the left and allowing the sprinkle to drop but it's not, making this level near impossible to complete unless you get the exact right power-ups in the right positions. For a game that's been around this long, I'm surprised it has bugs like this.
