The only way I know is on April fools day. The Coffee shop and Gift shop turn invisible.
You can't walk through walls anymore on club penguin but you can walk on walls. If you download Internet explorer 7 you can walk on walls of club penguin.
To walk on walls: First go to the fish cooler in the light house and click on the door. Then, quickly click the top sign. You can now walk on walls :-)

You can not do the moon walk on Club Penguin unless you are using Penguin Storm by MicroChip123. Even then people will not be able to see you doing it.

To walk on walls with people seeing you you must download a file. But there are alot of things to worry about. 1. You will get banned! 2. If you do run this file you will EASILY get a virus. So in my case DON'T download it.
