As you all know, there have been rumors all over Club Penguin that Rookie is a new famous Penguin Mascot. Well, those rumors are true, you need to Find Rookie during the 2011 April Fool’s Party in order to the Rookie’s stamp and Rookie’s background! We have proof that both exist. You can see the stamp in your very own stamp book and we were able to locate the item sprite for Rookie with a preview of his background, which are both shown below.

Just use your favorite Club Penguin Rookie Tracker and cross your fingers for a little luck! We haven’t seen the full background for Rookie, but what do you think of the snapshot preview? Looks pretty cool with the box dimension in the background! Here’s the full-sized Rookie background!
