This is a little thing, but I think it'd be funny. I'm playing through VV2 again and every once in a while, there's a small explosion. It's usually when I'm near the Research table. So...what if when the explosion happened, there was a tiny mushroom cloud? Nothing detrimental, just smoke to go with the bang. Or maybe with the explosion, someone turns green, like they got some gunk on themself. Then he turns, shakes his head and "Going to take a bath" pops up.

And villagers doing cannonballs into the pond cracks me up everytime. Keep that.
