Tomorrow, as revealed by Businessmoose, Club Penguin will most likely update the igloo features for a totally brand new igloo experience. Club Penguin has changed so much over the past 4 years. They've changed quite a few rooms such as the Book Room, the Mine Shack, the Dojo and the Beacon! There are more underground rooms now such as the Cave Mine, the Hidden Lake and the Underwater room.
There are more servers and the friends list has changed, and now the igloo features will change! It is hard to get used to change, but it has to happen. Some penguins may not like what Club Penguin is doing, but others do. These new advertising parties aren't fun, in my opinion, but it's great to have change. Club Penguin was better when I was smaller, but this is 4 years later. The PSA is long gone and the EPF is here.
