Club Penguin is an excellent online game. It is made by Disney, and is free to join. BUT, if you want to unlock all of the features in the game, you need to pay a small fee. Also, on Club Penguin, You can become: A Secret Agent (Shouldn't of said that!), A Tour Guide, A Pin Collector, A Puffle Raiser and many more things. It is one of my favourite websites. =-D Waddle about, and meet new friends!
Panfu is a game, similar to Club Penguin. It is brilliant. =-D
Please Note: There will be more games on this page after time. I am still hunting for them. P.S.: Don't forget to E-Mail me links to good games that you like!
