How would you think the ponies of Equestria would view ponies and horses here if they saw them?

I think it might be a surreal, almost uncanny experience for them, not unlike how it might be for humans when meeting a close relative that isn’t quite on the same level of sapience, such as a chimp or gorilla.

The first thing would be that they would be surprised that they don't talk and probably won't even be able to understand them.

As we see apes - something a "bit like us", but ugly, scary, dumb, and stinky...

In all honesty, I can't tell who is really the scared one here be it Twilight, Megan, or even those two horses.
