So, my 4 year old kid is suddenly wanting everything pokemon when we found the pokemon section of Epcot Japan. I've seen a few episodes of a cartoon decades ago, and I know there are video games and maybe an actual card game(?) as well as toys, but where do I begin? Is there a good intro show to start with? What toys/games are for the younger crowd? I grabbed some Pokémon XY off Netflix but that is about it so far.
