Since I don't know how to make a picture, I will describe where I put the arrows.
Left bull after door right to blue arrow, next possible left, log in, back, next possible down, left, log in, back, down, left and done.
Bull 2nd to left, straight up, first block left, before bridge, up, left, down, left. Done
Last bull just goes to open the gate for the cow.
Cow goes one empty left, after gate up, right over button, by wall down and through the bottom door.
I hope this helps. Sorry it had to be in English, but my German writing is not
good at all.
