Did you know that if your a member, then you have a VIP access into Club Penguin? Well, here it is, something I never thought anyone would notice but if you are not a member, then you will most likely won’t be able to get into something that is 3/4 of the way full. Like the chart below.

This chart shows that if a server is filled up to 3/4 of the way, then after that, only members can get in. That is what the Red area means. The Blue area allows anyone to get in, member or non-member. But after that bar is full of people, then only the people who are members can get in. Like a VIP line.
Here is another couple of pictures to help you out.

This Server above shows how full it is when you are a “non-member”.

While this Server shows how full it is if you are a “member.”
See the difference? Members get a little imaginary VIP pass that allows them to go into a server if it isn’t completely full, but doesn’t allow non-members even if it is under the same conditions. You may cry if you want, I have a tissue.
