Who of the penguins appears every 3 months or at a smaller time on club penguin?

Rockhopper Cadence and Penguin Band appears every 3 months or at a smaller time on club penguin. Club Penguin was divided into various rooms and distinct areas. Illustrator Chris Hendricks designed many of the first environments. Each player was provided with an igloo for a home. Members had the option of opening their igloo so other penguins could access it via the map, under "Member Igloos".

Members could also purchase larger igloos and decorate their igloos with items bought with virtual coins earned by playing mini-games. At least one party per month was held on Club Penguin. In most cases, a free clothing item was available, both for paid members and free users. Some parties also provided member-only rooms which only paid members could access.
