Updates on the 19th of January have happened in 2007, 2009, and 2012. There was also a mobile related update in 2014.
In 2007 there were three different updates. There was a new pin, the first ever Winter Fiesta party, and the first ever igloo flooring was released! The new pin was the Cactus Pin and was Club Penguin’s 24th pin. It was located in the Coffee Shop. It was the second pin to be hidden in that room. At the Winter Fiesta the free item was a pair of Maracas. As for igloo flooring, you could buy the Terracotta Tile, Maple Hardwood, Green Carpet, or Burgundy Carpet. Previously you could only have an igloo and furniture but no flooring.
2009 only has one update. A few login screens advertising what members can do were added. Here’s an example of one:
In 2012 there were a few updates. The furniture catalogue was updated with new underwater furniture, an Underwater Expedition login screen was added, boxes for the party was added, and the 65th field op was released. The 65th field op was located at the Cove and the game was to figure out the symbol combination.
In 2014 Club Penguin added more rooms to their mobile app. The newly added rooms were the Forest, Cove, Mine Shack, and Stadium.
