Puffles

Puffles are small, fluffy creatures that players may have as pets. They are available from the Pet Shop in blue, green, pink, black, purple, red, and newly released yellow. Non-members have access to the blue and red puffles and may have no more than two; members may adopt up to fourteen puffles. Puffles have health, rest, and energy bar charts to indicate their status.
There are seven official breeds of puffles, each with a different personality.
Blue Puffles are mild tempered and content. Their favorite toy is a ball. Blue Puffles are special because anyone in Club Penguin can adopt them. Blue puffles are also special because blue puffles were the first puffle breed in Club Penguin. Blue puffles are loyal, for which they are popular.
Green Puffles are very energetic and playful. They like to clown around on their unicycles or play with their propeller caps.
Purple Puffles are lots of fun to have around. They enjoy blowing bubbles and are terrific dancers, but they can be a bit fussy, especially at mealtime.
Red Puffles are adventurous and enthusiastic. They are fearless when attempting daring tricks (except in the survival mode of Catchin' Waves) and spend a lot of their playful energy on a surf board. They shoot themselves out of a cannon or bowl when playing. Rockhopper brought these puffles to Club Penguin on his ship from Rockhopper Island. These, like the blue puffles can be adopted by anyone on Club Penguin.
Pink Puffles are very active and cheery. They love to exercise by jumping rope or playing on their trampolines.
Black Puffles are known to be a little mischievous and off tempered. However, they love to play and make a great pet for anyone who likes a little bit more personality.
Yellow Puffles were added November 30, 2007. They love art and are very active. Their superplay (that's what Club Penguin calls playing with all health bars filled) is filming a movie. Otherwise, when asked to play they paint. They sculpt their food into a book room ornament before eating it. Taking it for a walk then dancing makes it sing. Upon bathing, it adds coloring/ paint to the water. when you put it to sleep it dreams of being a super hero.
According to the book Truth or Dare found in the Book Room, the green puffle dancing on the speaker in the Night Club was the rumored "Keeper of the Boiler Room".
