Club Penguin is a snow-covered, virtual world where children play games and interact with friends in the guise of colourful penguin avatars. Players create a penguin and explore the snow-covered island of Club Penguin, engaging in a variety of fun and imaginative activities.

Players can chat, send greeting cards, use emotes (emotion icons), or choose from a set of pre-defined actions such as waving or dancing. Users can also attend parties and special events, take on a role in the latest stage play, adopt and care for a cute and cuddly puffle pet, and play games to earn virtual coins which can be used to design the perfect igloo and create hundreds of outfits for their penguin.
