I was thinking...

If water does return, and so does Day/Night... Why not have the areas flood at night? Ancestral Steppe would flood in the area next to the river, and underneath the area with the vines. Ludroth, Gobel, and Bubbles could live there. Frozen seaway would flood in the area on the frozen ocean, Zamtrios and Glacial Agnaktor underwater? Most of the Sunken Hollow would flood, making a neat network of underwater caves to explore. Plus it would wash out Khezu and Gypceros.
