My question is...
Is there any script in the map editor which makes each animal moving ALL OVER THE ISLAND, in random directions?

 ai_center:ai_center UnitID
 unitpath to let the animal go along a predefined path. I think the center/spawn logic is ignored while following a path (I'm not 100% sure though). Also it's not random then so probably not what you want.
