Yes, Club Penguin is a virtual world for kids and is great if you would like to make new online friends or talk to your friends in real life on it.
webkinz is quite like club penguin but not as good with chatting. A good one is tootsville or chobots.
Club Penguin (however club penguin is mostly for younger kids)
I recomend Secondlife and Wizard101. Club Penguin is fun for kids and girls like Stardoll.
