The sheep are trapped in each corner by fireflies bottom left, oysters bottom right, flowers top right and iced crops top left!! We don't need to collect all of these but they do need to be moved, to get the sheep out. Start with getting the fireflies away, and then at least 1 of the other blockers. There are 5 hay square's in the middle of the board, and a conveyor belt around the board. Get the sheep onto the conveyor belt, and then work on moving them to the hay. The crops collect themselves as you go but just keep an eye on your count.
