So you know how there are pokemon who spawn in the water in the safari and water tiles? well, there are these random ponds in towns that seem empty. What if. like one pokemon spawned in each pond so you could walk around and see a random karp or barboach or something. It would make towns seem much more alive.
for those pokémon to be wild-spawning and catchable would require a fundamental change to the map's seed generation process, and as such is not really viable at the moment. they could be added as NPCs but there's too many towns with ponds in different spots to do manually and im not smart enough to automate their creation (especially if we want them to move around in the ponds).
