Calvin & Hobbes have a Transmogrifier. James and his parasaurolophus, Max, have a TransGROWLifier. Different, see? TransMOG, TransGROWL. Different.
This multi-functioning super machine's main feature is, of course, the Transgrowlifier itself, which transforms you into anything you want to be (mostly animals).
It comes with a button,
and a dial.
Next we have the Time Machine,
in which you may travel to the future,
or the past.
And last but not least, the Duplicator,
which will create for you either a good copy of yourself, or for the more enterprising, your evil twin.
There you have it, folks. Don't forget to bring along your tasty lunch. :)
