The Penguin Band is Club Penguin's most popular and official band. It is made up of four penguins, G Billy, Petey K, Stompin' Bob and Franky. There once was a scavenger hunt when penguins had to find the Band's instruments. Once players found the instruments, their penguin was rewarded with a player card background featuring the band and their autograph. Another background was given out during the Music Jam party when the band went on break. Like Rockhopper, the band members can be seen sometimes during certain parties, on random servers signing autographed backgrounds and talking to penguins. They are the only official band known in Club Penguin.

Penguin Chat 3 Band

A group of musical penguins resembling the Club Penguin Band existed in Penguin Chat 3, which were proven to be the Penguin Band on the Whats new? blog. There were a few differences, listed below:

Everyone in the Penguin Chat 3 band wore the old colour Old Blue.
There were only three members of this band, because Franky hadn't joined yet.
The piano that one of the penguins used was brown, not black.
A flute was never used in the Penguin Chat 3 band.
The band played around the clock at the Dance Club. There were not any speakers or disk jockey stations in the room.
In the only known picture of a Penguin Chat 3 performing in public Igloo, the PC3 Band is inexplicably depicted as playing in the igloo. They are playing many songs which change time-to-time, one of them is "I've Been Delayed" by a band called TAS1000.
