You MUST use a Gmail email account for this cheat to work.
Go to
http://play.clubpenguin.com/create_account/1. Tick the Club Penguin Rules box and press continue.
2. Choose your penguin color and press continue.
3. Next choose a penguin name and continue.
4. Now enter a password for your penguin and tick the terms of use box.
5. Now here’s the important part:
6. When entering your email add +1 just before the @gmail.com
If adding +1 doesn’t work then add +111.
Now even if that email address has already the maximum of 5 club penguin accounts created on it, it will still work!
there you go your welcome ............................some credit to Ojoc
