Well... [He hesitates for a moment, still not entirely sure about all of it.]

Apparently, ponies are the natives in this place. Everyone who lives here is some kind of pony...an Earth pony, or a unicorn, or a Pegasus...

And apparently, the locals are pretty used to, uh..."off-worlders"...like you and me...arriving in this town. It's a bit of a problem that's been happening lately.

But when off-worlders arrive, they're turned into one of the kinds of ponies...probably to fit in better...
