15 Moves (revised)
2 White Sheep
2 Black Sheep
This level can be tricky but can be a fun one.
You know you need to move the sheep to the hay, but you only have two pieces of hay so you need to move the white sheep first as the black sheep will nom nom it.
Then you need to make as many crops as you can cascade, hopefully some of them will land on the grass and those points will add up.
Don't fret if you don't do it quickly though as the level won't always let you win easily.
