You are a Pokémon trainer, and you're in a heck of a pickle. You came across a Vaporeon while trudging through a swamp, and wanting to catch it and add it to your team, you challenged it to a Pokémon battle

By the time you got to your sixth and final Pokémon, the Vaporeon was sitting on its butt, its gut full and squirming, the sound of water sloshing clearly audible
