CAN Bill enter the physical world on his one will? I always thought that he has to have a "gate" of some sort (I.e., summoning, portal) set up in the physical world. And even then, he can't really exist; he has to freeze everything, so presumably no time will pass. Stan's portal almost definitely has something to do with Bill. I think that the purpose of the portal was to summon Bill when Stan wanted (by pushing a button or something), but maybe the portal actually opens for BILL to enter the physical world whenever he wanted, and Stan just didn't know that. Also, the portal was said to open to "info it worlds". Maybe one of those "worlds" is whatever dimension Bill resides in.

So Stan could have just opened a free door to Bill. Or whatever other monsters are living on those worlds.
