Yeah, if you login from this link, you will see a foggy room. Unfortunately, it may lag and your penguin is at the top left corner.
The good thing, is that you can see a blurred shadow that looks like a giant puffle-shaped dome. Right next to it is somewhat a penguin holding a puffle. Since there is less party rooms for Muppets, there may be exciting ones WITH main room decorations for Puffle party.
