I would definitely agree with Tentacool being available early on as well as Seel being pushed back some. I know Seel and Dewgong aren't really used all that often, and are outclassed by better water types. Tentacool with early poison type would help against Florinia, but I think if it was available before Julia, then it would have the floor wiped with it. Also, with Vulpix, I think it's fine in Obsidia, but maybe change the requirements so that it's available later on instead of before Florinia? An example would be to have your starter, with max happiness and at level 40 or so. (or anything really, just to make it harder to acquire). It could probably do well on 7th Street too if you were to push it back anywhere.
