The build was released in a joke announcement made to CP3D's official Discord server, stating that it was the "final build" of the game, and that the game would cease to be developed further. The build features intentionally bad player models, and only one room, being the Box Dimension.
- This build was the first time that CP3D was playable to the public. Penguins created for this build did not carry over when the game officially opened.
- The build's announcement was not well-received by many, especially those not active in the community and did not recognize that the announcement was a joke.
- The Penguin Band played in the Box Dimension during this party.
- Attempting to leave the Box Dimension would present a player with a fake membership popup, parodying that of Club Penguin Island's.
