you were just minding your own business on the couch, sure. you COULD be outside trying to catch Pokemon, but you just don't feel like it today. then you hear a knock at your door, you go to answer but when you do there's nobody there... you then look down to see of all things - a Pokeball. you pick it up, you just KNOW there's something in it! you let the thing free in the living room and... it's a Litten!
