Wow. EA's Pet Society is definitely getting greedy. The new digging place "Deep Ocean" costs blue coins if you want to purchase additional digs. I definitely do NOT think it is worth paying real money to "dig" in a virtual game. But there are lots of rich people out there I guess :p
Lots of new stuff out too. Dragon Petlings =D Should be possible to get it if they did not change anything. Will take a look later. Stay tune!
