Old MacDonalds sheep station is suffering from a nasty drought. The sheep are quickly running out of grass, and all grassy paddocks look more like prickly hay bails! The neighbouring station has plenty of grass but is very far away. Cross more than 100 levels of barren deserts, haunted graveyards and snow-covered wastelands over four stages as you complete tricky puzzles and puzzling obstacles to get to the fresh grass. There are also hidden secrets along the way. Try to find them all for the biggest highscores and bonuses!
