Pokemon stadium is what would seem like pokemon stadium 3,but really,it is just a change in pokemon games.A bad change.
It starts off with a teen geting a item called the snag machine.From there you can capture showdow pokemon.These pokemon are pokemon with a dark aura and your partner can tell which pokemon are shodow pokemon.They only have one attack and will sometimes hurt the trainer you are battleing.You have to capture 41 shodow pokemon.After taht it is over.
The good thing about this is that if you have pokemon ruby,sapphire,firered,leafgreen,or emarald,you can catch rare pokemon like the three cats,and Ho-Ho.Other than that,if you dont have any one of these games,then do not get this game.
