The cbox's floor tends to change composition from time to time (usually when there are not two more chatrooms above it). Sometimes it's made of vinyl tiling; at other times, it'll become lava. Sometimes it'll have no ground cover whatsoever, allowing members to burrow up into the chatroom easily. Every now and then, when it is not a chat tower's lobby, the cbox's floor will be comprised of floorboards. In general, said floorboards were used by various members to stash away their loot and/or subterranean exploits, until the floorboards were forgotten in 2010.
