I currently require about 4000 diamonds to get animals to do quests. I actually have about 6 diamonds and impossible to get them on a regular basis, even to hire a worker its 14 diamonds so you have to do everything for yourself. The makers just keep saying you get them by playing or getting jigsaw pieces to acquire animals. I suggest they try playing the game themselves to see how difficult this game is . DONT SPEND YOUR OWN MONEY GUYS ITS NOT WORTH IT.
