Well, since you can't find either in the wild in Platinum, my fiance' and I would like to get Caterpie and/or Weedle to add to our collections.... :)

She'd greatly prefer a female, but it isn't a major issue, and I'm not picky either way, frankly...; if you can help, reply here or send me a message, and I'll see if we can work out a trade deal!

I can get you a female Caterpie from Heart Gold.
