Oh this is just
brilliant. Alternate worlds, parallel dimensions, alternate dimensional worlds; pocket universes, bubble universes, I love them all really. Well not all, some of them have been a bit of a bore, others a bit smelly. This one smells just fine though, a bit metallic but also a hint of cinnamon. Tastes a bit different too, that's how you can tell it really is different. The grass tastes a bit gross. Sadly.
Anyway, hello! I'm The Doctor, lovely little town you've got here. It's always the little towns where the strange events occur isn't it? Big ones get the big events, little ones get the tiny unnoticeable events that are strange and mysterious. Very cliche, but brilliant. Stick with the classics, that's what I always say... actually not really sure I've ever said that before.
Back on track though, seems you've got a wormhole problem; it's okay, happens to most dimensions this age, definitely something I can help with I think. Though this one is just a bit more complex than I've ever seen, feels different in that way. Totally into it, love a challenge, and I guess this means I'm here for the long haul. I don't usually do the long haul, it'll be different...
Suppose this means I'll need to get a job. Only had a job once before, for half a day. How do you get a job?
