DJ3K (sometimes referred to as DJ3000) is a mini-game in Club Penguin Rewritten. The DJ3K itself was invented by Gary the Gadget Guy. In the game, players can press the buttons to make songs. The longer your song goes on and the more sounds you add to it, the more coins you will earn. The game is endless, and you can collect your coins by clicking the "X" button at the top right. You can bring your yellow puffle along in the game and it will dance and earn you more coins.
