It needs 38,4000 to complet koala habitat. It is too much for players at present.We will spend months on earn money to level up only one habitat.
{ supposing 50 coins/per hour * 10 habitats * 3times/collection= 1500 coins
1,500coins* 30days= 45,000coins
45,000*8months =360,000coins
and there is no fun at all for this purpose. We can not construct the beautiful zoo as we want originally.
before it cost only 2 gems whatever the price of the animal is.
