In case you were wondering, it is indeed pretty cool! Pokémon Stadium has made its way over to North America, so without further ado, celebration! (i.e. the screenshots)
But there's more than fierce battles! There are fun mini-games like Rock Harden, Snore War, and, shown here, Sushi-Go-Round!
To play Pokémon Stadium and upload pokémon you have on Pokémon Red, Blue, or Yellow, you need a special game boy adapter that plugs into the N64 controller, like a memory or rumble pack. Don't worry, it comes with the game.
