The restaurant connected to the Striaton City Gym, among many other idiosyncrasies, is notable as the last establishment in Unova to still serve water poured by Simipour.

For much of Unova's history, however, one could scarcely find a restaurant or inn without one, and any family which could afford a Panpour and a water stone would eagerly snatch one up for themselves. In this era, before artificial water filters, fresh water was rare, and pollution from humans and pokemon alike ruined the taste of many rivers; in heavily urbanized Unova, it was rarer still. People instead hydrated themselves in a variety of ways, such as fruit juices and alcoholic beverages, forgetting the taste of water, a relic from a bygone age.

The majority of water pokemon absorb water from their environment. If the local water has a nasty taste, so will the pokemon's attacks; if the water is heavily polluted, the pokemon will become sickened. Yet no matter how much agricultural waste flooded Unova's rivers, Simipour could be spotted pouring water from their front hairs onto suffering pokemon and into their mouths - and that of many a curious human- unharmed by the waste which sickened everything else in the water

Simipour at the time were thought to be natural water purifiers, although more recent, severe pollution events have shown this to be untrue. But these pokemon do have a remarkable ability to find even the most hidden sources of pure groundwater, and their watery hair provides them with a way to share it with the world – human and pokemon alike. Drinking water, once so polluted that it had been all but forgotten as a drink for humans, became a Unova-wide sensation, which it remains to this day, although the Simipour themselves have been supplanted by filtration machines.
