Puffles are small furry pets native to Club Penguin Island. Puffles were first discovered in November 2005, and were first adoptable in March 2006, being sold for 800 coins, which has since been reduced to 400 coins. Puffles are small, limbless creatures who eat Puffle-O's and other foods native to Club Penguin.

Over the years, twenty additional species of puffle (including real-world animal counterparts) were officially recognized and discovered. Of fourteen, ten are permanently adoptable for members, two Puffle Creatures are permanently adoptable at the pet shop, two are adoptable for non-members, and six were temporarily adoptable at Prehistoric Party 2014. The Rainbow Puffle and Gold Puffle are adoptable via quests starting at the Puffle Hotel Lobby and Pet Shop, respectively.

The Blue Border Collie and Orange Tabby Cat became the first two permanently adoptable puffle creatures just prior to the Puffle Party 2014. Snowman Puffles became available at the Frozen Party, and Ghost Puffles became available at the Halloween Party 2014. Most recently, a Blue Crystal Puffle became available at the Merry Walrus Party, after appearing in the TV special We Wish You a Merry Walrus.

There are Puffle Parties that have been held in either February, March, or April since 2009. Each puffle has their own special area (during the Puffle Parties) and, sometimes, there are discoveries of new species..
