I feel like Shellder and Cloyster, Clauncher and Clawitzer, and of course Magikarp would be found all around my area. Probably put a "very rare" label on Spheal and Seel, too. Wingull would be found anywhere inland but especially in Johnston where they love to feast on the dump that we call Mt. Trashmore. Speaking of Mt. Trashmore, Grimer, Muk, Garbodor, etc. (typical Poison smorgasbord) would probably be found there... and would probably be home to a Poison-type legendary mon.
In my city proper, there are a LOT of trees, so I think Sudowoodo would be a fun addition![]()
