110 Water drops
2 Black Sheep
6 White sheep
Do not move the black sheep before the white ones or you will lose all your hay.
The idea is to move the sheep onto the hay if you can when they are next to the side, if you can't move it onto the hay, then at least move them onto the grass.
Try and move more than one sheep at a time.
Once you have moved some of the white sheep, it doesn't matter if you move a black one as well at the same time. The white sheep will always go to the hay first, just make sure you haven't used all the hay.
Now you have got your sheep, use cascading crops and combinations for the crops.
