Uhh, I can't say that I have ever seen pig wrestling so uh...yeah. [He laughs a little.]

Didn't you say last time that she's kind of shy though? That may be why she hasn't evolved yet. My Bulbasaur was the same way, just a bit of a late bloomer...literally, in his case. I think he was a little nervous about evolving, myself. Mostly because he's nervous about everything new he comes across, even now that he's a Venusaur.

Or maybe she just doesn't want to evolve for one reason or another.
