Sheep Herder Valley

The Challenge:
Move mountains, herd sheep.
The sheep have escaped and are on green grass hill.
Herd your flock of 100 sheep back to the paddock by sliding the hill - but other mountains may be in your way, slide them first to manoeuvre your hill, you'll need to think carefully about how to move them to clear a path for the hill with the flock of sheep.
Each level has a minimum number of moves it can be solved in, be careful if you take too many moves the sheep get lost.
