As you know, there was something invented by Rocketsnail, AKA Rsnail. And it was invented BEFORE Club Penguin. It was called Penguin Chat.
It was very fun to play, it was almost like Club Penguin today! (Hear that? It's a poem!) But after that, Club Penguin was invented. They threw a great Beta Test party. And everyone there could get a free beta hat!
The Beta Hat is the most rarest item on Club Penguin, that's why people with beta hats today might not come on often, or they're REALLY hard to find.
