CLUB PENGUIN IGLOO QUESTION!?!?

Ok so I have been playing Club Penguin, and was visiting some igloos. When I was visiting them there were many igloos with two floors. On those floors I realized that the upper floor was dance and the lower floor was carpet. How do I make my igloo look like that? If you don't know what I'm saying visit this link: a href="http://imageshack.us/photo/my-images/131/laggingigloovn3.png/" rel="nofollow"http://imageshack.us/photo/my-images/131…/a .If you visited the link you saw that there was part blue carpet, and part green carpet. How do I do that?
