Oh shoot, I thought I replied!
I just realized I think I have a Caterpie in my box; someone traded a baby for one of the ones I sent. So yes, the Caterpie should be good to remove and we can use a Mudkip perhaps. :)
Did you still want Kakuna? The one I caught is useless to me and I was going to say goodbye to it, but I'd much rather trade it and give someone else a chance to breed it, then pass it to the next player. :D I got my Beedrill from it and, if I ever need to come up with another, I can breed babies with that one. :D
I got all of the land Pokémon now; I just need surfing and fishing catches now. Need Seel from Giant Chasm, Barboach from Route 8, and a few others from the eastern Unova and I'm all done. From there, it's time to evolve and hatch babies to complete those entries, then it's time to try to set up a Trade Shoppe with my own list of missing Pokémon. :D
Also, if you can get me any of the other starters (Treecko and Torchic for Gen. III, anything from Gen. I, and - if I can't get any SS trades finalized - also anything from Gen. II), that would be exceptionally useful. I do have some Pokémon from White Forest due to trades; Magby, Machop, the aforementioned Caterpie, Gastly, and a couple of others are hanging out.
