The peeps in both versions of VF never seem to notice the rain, although I've seen a couple of young ones "scared of the thunder/lightning".

In most, maybe all, the VV games that include rain any nursing mothers make a dash for shelter as soon as it starts, as do any peeps that dislike rain. I can't haven't seen anyone in VF who dislikes rain, but all the same, I would have thought that unless a peep especially likes rain they'd run for cover anyway. The 'civilized' peeps in VF are surely less tolerant of rain than the hardy villagers in the VV games. They surely wouldn't be holding barbecues!
