On the 23rd of February Club Penguin has updated in 2007 and 2013. Each year there was only one update. In 2007 the clock tower was added to the Snow Forts and in 2013 the Silver Award item was now available at the Hollywood Party.
Up until the February 23, 2007 the Snow Forts looked like this.
Then the clock tower was added, making the room look like this. The clock tower follows PST, Penguin Standard Time, which is really just Pacific Standard Time. Having a clock on Club Penguin made meeting up with a friend easier.
As for the update in 2013, at the Hollywood Party’s award show you could now obtain the Silver Award trophy as long as you were a member.
