Penguins are the primary inhabitant of CP3D. They are the main species and control almost all of the island's civilization. Some penguins get so famous that they become mascots, such as Rockhopper and Gary.
Penguins can do many things such as play minigames, adopt puffles, chat, clothe themselves with clothing, and decorate their igloos with furniture. Player Cards are used to manage their own customizations and interact with others.
