Pretty Sheep

Oh no!! the sheeps have escaped!!

Our little shepherdess is in trouble, help her reunite the flock before the day's end or she will lose her job!
Bring back all the sheeps to the fold but beware they don't run away again, they're pretty naughty!
And if that wasn't enough a gang of thieving wolves are behind then, d'oh!
