Peter was relieved to find that there was actually some real nature to be found not far beyond the bounds of the resort, part of him had been worried they'd just wander their way further into the city and not find anything for Carol - which would be really sad.
But they'd had some luck finding themselves out in a sort of field of sorts out a ways from the hotel and sort of just wandering around on the off chance that maybe they'd find something? Honestly, Peter might have pretended like he knew what he was doing, but it was all mostly just teasing Carol - he didn't have the slightest clue what they should be doing.
And just like that there was a wierd little sort of mouse thing - not an actual mouse, the same way that Bulbasaur was not an actual dinosaur... or lizard, or plant, he was his own sort of thing. And that little mouse seemed to be the same way - so that seemed like they were in a pretty good spot. When he caught sight of the glowing though Peter's eyes went wide, "Uh, I mean - I guess it depends on what you're gonna do." He said, "But I think we've got a better chance of finding something out here than we did back there."
