Club Penguin is a civilization. When one civilization one come along years later to take its place. Just because the Cove and Forest weren't discovered until modern day, doesn't mean they didn't exist millions of years ago.

Besides, I kind of agree. Club Penguin already has already a broken timeline as it is. :P
