Players in Club Penguin can find special penguins waddling around referred to as Mascots or Famous Penguins during special parties and events. These penguins include Aunt Arctic, The Penguin Band, Rockhopper, Sensei, Rookie, Gary The Gadget Guy, PH and Cadence. These penguins are controlled by Club Penguin, and when a player is in a room with one of these penguins, they get a special stamp and can click on them to see their player card. In their player card they can friend the mascot or get an autographed background from them. They cannot, however, view their stamp book or any of the other things a penguin could normally do from the player card. Finding one of these penguins is very hard because they are only on one server in one room at any time.
