Well, this is something you've probably never seen before: a fish playing Pokemon. Over on Twitch, there's a channel called FishPlaysPokemon (did you think it would be any different?) where they have Grayson Hopper, the fish in question, playing Pokemon.
The channel explains: "Hi everyone! Welcome to our stream where our fish, Grayson Hopper, plays a Pokemon game. Unfortunately, we don't have a dedicated light for Grayson at night as he lives in a tiny dorm room and we would rather not sleep with the light on. :( But in the future we will be getting him a dedicated lamp and improving the quality of the stream to include recent inputs determined by the motion tracking. Things can move a little slow, so another option we're considering is making the system distributed where we have a site where you can provide a fish stream link and we'll include it in the controlling".
Right now there are 17,877 people watching, with a total of 1.17 million total channel views. Grayson has been playing Pokemon for around 125 hours, and now has a Charmander named 'AAAABBK' and even defeated his first opponent, the rival's Squirtle.
