The hat itself works in any world. The doors are subordinate to the hat, that is, there are doors on all worlds, but you can only use them using the hat. This means, for example, if I leave the Enchanted Forest and go to Wonderland, I have to go back and forth, but I can not get out of Wonderland without using the hat. That's my theory.
