31Z TELEPORTATION ROOM. Wiggling up the tubes from 31B leads to this room, about thirty feet up. Against the south wall is a small passage that leads to the top of the structure. On the wall next to the passage is a metal box with a horizontal slit in it.
Placing a data card from Room 31W in the slit will allow a person to teleport without error. The site that the person is teleported to will match the data on the card, corresponding to the address of a child who has lost a tooth. If the tooth has been replaced with a silver coin, the teleportation device will return the person to this location.
The top of the tooth tower is shaped like the top of a molar.
