Redesign is the process of changing, updating, or simplifying features or aspects of Club Penguin. There have been five major redesigns in Club Penguin history, all of which happened after the purchase by Disney.
First Penguin Redesign (2008)
In 2008, shortly after Club Penguin's purchase of Disney penguins were entirely redesigned. Differing from their previously triangular shape, they appeared pear shaped and more detailed. The design remained until 2013.
First Room Redesign
Beginning in 2009, new rooms that were drawn changed style. Old rooms remained the same, but new rooms were drawn with lines as opposed to the fill in shapes that appeared in older Club Penguin rooms. New rooms that appeared on the island from this point forth appeared in this style.
In March 2011, puffles were given a new art style. They were made to appear fluffier and more like pets. Their in-game appearance as well as their artwork changed to match this new style. They appeared larger in a penguin's igloo, so penguins in igloos were also made slghtly larger. The old puffle look can still be seen when playing Puffle Roundup.
General Interface Redesign
From late 2010 to mid 2011, the interface and other aspects of the game were just generally revamped. The map was renovated, a new puffle interface was launched to compliment the new puffle style, and several games received new start screens.
Second Room Redesign
See The Journey (Big Update).
Beginning with the renovation of the Book Room following Marvel Super Hero Takeover 2012, several rooms received new designs. The largest group of these happened following Operation: Blackout. The renovation is still considered on-going with the renovation of the Dojo, Dojo Courtyard, and others following Card-Jitsu Party 2013.
Second Penguin Redesign
Beginning in 2013, penguins were also drawn in a new style. They are now taller, thinner, and more humanistic. Lines appear in a darker variation of the subjects color, a style often called saturationism. Beaks are no longer round, and appear more orange as well as longer. All mascots were given a body item.
