2 Black Sheep
180 Water drops
Don't be tempted to move the sheep down too early, otherwise they will be right above your firecrackers, and will be in the way.
Clear as many of the firecrackers quickly as you can in as few moves as you can, then you save moves for moving sheep or gathering crops,
You need points on your crops, make +5 of any crop even if its not a collectable one as it will add points to the rest.
Once your firecrackers are clearer, start moving your sheep towards the hay. Don't leave it until last minute as you could run out of moves.
