What happens if the Tardis goes through the Phantom Tollboth?

I think the Doctor would be at home in the lands beyond.

"Pardon me," said Milo to the first man who happened by; "can you tell me where I am?"


"To be sure," said Canby; "you're on the Island of Conclusions. Make yourself at home. You're apt to be here for some time."

"But how did we get here?" asked Milo, who was still a bit puzzled by being there at all.

"You jumped, of course," explained Canby. "That's the way most everyone gets here. It's really quite simple: every time you decide something without having a good reason, you jump to Conclusions whether you like it or not. It's such an easy trip to make that I've been here hundreds of times."
