"Of a Water Gym you expect water, yes? True, Buna's Gym does have it's fair share of water...Apart from the gleaming tiled 'reception' everything else is covered in muddy rock and dark blue 'ponds scattered about the room'. Underneath the earth floor is a series of tunnels connected to a main pool. Using these water pokemon may travel freely between the seven pools on the surface. It makes things more interesting, no? If the humidity didn't already."
