Here's what you need to know:
* In the Pokémon games: Rotom can be found in the TV in certain locations. You can catch it by using a Poké Ball, and once you have it, it can be switched between forms by using the Rotom Catalog.
* In real life: Rotom is a fictional creature, and it's not possible to have it in the real world.
It's important to remember that Pokémon are fictional creatures that exist only in the games, anime, and other media. Enjoy the fun of the game and let your imagination run wild, but don't expect to see Rotom coming out of your TV!
