I've been trying to lap up the remaining Unown letters like water now, but I think my most recent catch was actually a Smeargle. It had an annoyingly low catch rate, so I am convinced it's a rare encounter.
Well, it wasn't any of the 3 Unown I'm still looking for... ...but at least I know they aren't just a myth!
I figured I'd want to eventually train for a bellossom, so I caught both oddish variants. I don't know which will end up as a vileplume or bellossom... so it will be interesting to see. xD
Added a Corsola to my collection just now! And Poliwag right before that, which I surprisingly didn't have yet. now where is my shiny ;A;
