Box Portals have dated back in Club Penguin since the April Fools' Party 2007. If you walked to or over them, you would be teleported to a different room. The Box Portal that was most commonly used was the Box Portal that took a penguin from the Coffee Shop to the Beacon. The portals were made of, obviously, boxes. You could tell where it would lead because an item from that place would be beside it. (i.e. Coffee Shop's Bean Bag, Night Club's speaker, and the Beacon's Jet Pack).
