The dragons are not so bad to get. Once you have broken the iced water underneath, move them down (hopefully by making a vertical crop row underneath) and make your dragons. Once they are lined up the iced eggs will break and off they pop.
The hardest part is making the water because of all the iced crops in front of the buckets. Break the ice as soon as possible, even if you need to use shovels. Then make as many rows as you can next to the buckets which will bounce around and hopefully land where you need them. Make rows out of water with more points on first.
