That isn;t the end of Pokemon you can see go on ( i think ) , but get the password , go to the warehouse ( Island 5 ? ) and then do the maze ( if you look online someone will have a video on youtube , Google videos , or a walk through that will tell you where to go to get through it if you are struggling , then defeat a few more team rocket with your Pokemon ,, they normally have types like Muk , Golbat , Raticate possibly fearow and an electric type , like before in Saffron City but higher leveled so be careful
battle the red gyrados at the lake of rage and then go to the souvenir shop
you get it at team rockets hide out
