DJ3K is a mini-game in Club Penguin Rewritten. The DJ3K itself was invented by Club Penguin Rewritten's resident inventor and scientist, Gary the Gadget Guy. DJ3K is a way for penguins to create their own music for their igloo. It also serves as an add-on to the DJ Table in the Night Club. You can bring your yellow puffle along in the game and it will dance and earn you more points, earning you more coins.
