Haven't posted in this thread for a little while, but I've been doing well over the last few days in terms of finding things I didn't previously have.
Meowth and psyduck, two old favourites, came on Saturday, along with a grimer, all new to me. There were a few days then of not much new stuff coming from catches, but I hatched a rhyhorn on Monday and then yesterday a chancey. I also caught three new things yesterday; a geodude, a slowpoke and a gloom. Okay, I already had oddish, but was nowhere near evolving it.
Also been slowly building up candies for other things, most notably eevee; eevees are apparently common as muck elsewhere but I'm level 14 and have only seen 3 :/ I'm also one gastly off a haunter.
