While I didn't get any new dex entries from catches, yesterday was quite a good day. I got the eevee I've been wanting for aaages that allowed me to evolve my first eeveelution (let it pick at random, turned out to be jolteon), and I also got a bunch of stuff that I'm trying to get more of for evolutions, including catterpie, seel, horsea, oddish, magnemite and (this morning) voltorb.
