Echoing Hrae. Pidgeottos are becoming the new Zubat of the Safari Zone. Heck, I actually haven't seen Zubat too often anymore around here! :O Maybe they're all back in Dark Cave?
Swinub, and Sentret, and something else that begins with S, probably. Give it time; it'll show up. please no Stantler
I have decided that unless I encounter a shiny by some fantastic ever-against-me odds, I shall be skipping every mon until I have amassed a more comfortable level of Pokeballs. >_>
I think I passed over an Unown R this time? I don't remember that clearly. It was one of the letters. You too, eh? Pretty smart way to save your money if I do say so myself.
Sentret! Slugma! More things that begin with S! ...maybe S is just a really common letter for those sorts of things.
