Box Portals

Box Portals were used in both the April Fools Parties of 2007 and 2009. If you walked to or over them, you would be teleported to a different room. The one most used was the one 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.

Trivia

 * During the April Fools Party 2009, a item in the Box Stores catalogue was a box portal. If placed in a igloo, it will "teleport" you to a special room called the Box Dimension. It was only available to members, but non-members could enter the Dimension by using a portal in a member igloo.
 * They may appear at the next April Fools party.
