To keep their skin pristine, Vaporantis constantly bathe under waterfalls. If a Pokémon gets any amount of filth on them, Vaporantis hit them with Hydro Pump.
It requires a lot of effort to maintain Vaporantis's vivid coloring, but some collectors enjoy this work and treat it as their hobby. Vaporantis underwent a spontaneous mutation and grew fins and gills that allow them to live underwater.
