Several to many! Lots of Pokémon hanging around are a fraction of my size if that, and just looking at me is enough to cause many of them to panic. I can't say I blame them; imagine if a 15-foot dinosaur came up on an unsuspecting human. It wouldn't matter what soothing words that dinosaur said, now would it?

As far as other issues, mostly I merely envy being unable to burrow or hide like smaller Pokémon can. Climbing trees is quite easy, though!
