Inside a crate on level 1, you find
You open a stuck storage-room door and find...
A large cardboard box, open side to the floor, with "Transmogrifier" crudely lettered on the side. A paper arrow has been pinned to the side with a thumbtack, permitting it to rotate. Written in an arc (obviously to be pointed at by the arrow) are "Boy", "Tyrannosaur", and "Tiger". There is room for more to be written. If the box is placed over an object and the arrow set to one of the settings written on the side, there is a loud "BOINK!", and the object is transmogrified into a scale model of the item listed. (If this is used on a living creature, the creature is transmogrified into an example of the thing listed on the side, of the same size as the original creature.) The box is large enough to fit one six-year-old boy and a stuffed animal.
Caution should be used, as when on its side the box serves as a cloning device, and when set with the open side up it becomes a time machine.
