Always try and start the bottom fireflies first. You can ignore the ice, unless you make a row with it. More often than not, it will get broken with moves anyway. Once your bottom flies are lit, work on the top ones. You only need two moves for each one to make it glow, so if you bottom ones are glowing, and the tops wings are open, you can always use shovels.
The problem with this level is the rabbit again. We only need 45 carrots. But the rabbit keeps popping up. Don't worry too much about stunning him, although handy. As long as you can get a cascade effect with crops, points on your carrots will add up and if you have a good board, you will get all the ones you need. But its all about building points.
