>>19114903Lets use some fucking imagination.
Water, Flying, Ghost, Ice, Psychic, and Dragon can all feasibly appear in different water based environments. Pokemon with Levitate. Pokemon who just look like they float. Pokemon with Water Absorb. Pokemon with Dry Skin. Just about any of them can feasibly appear if you change the surrounding landmasses and depth of the waters.
Differentiate them by more than just pokemon as well.
Have one route constantly storm. Have another with crystal clear and calm water. Have a dank and dark route with lots of rocks sticking out and floating debris. Have a route with underwater steam vents sending bubbles to the surface. Have one filled with coral. Have another filled with magical fairy water.
Have one with moving landmasses. Have another ruins that emerge based on the time of day. WATER ROUTES DON'T HAVE TO BE JUST WATER GF.
