Schafe Schnappen (2007)

From the publisher:
Don't be a sheep, roll a sheep! The sheep are peacefully grazing on the meadow, enjoying life. If only the wolves weren't always annoying them and trying to coax them away from the herd. Who will stop rolling at the right moment? And who will risk enough—but not too much—in order to win by having the most sheep in his stall at the end?
