Team Rocket Hideout

Conveniently enough, you'll encounter a scientist inside Dotted Hole who will give you the second password.

To get to Dotted Hole, head to Six Island. From Six Island's town, head out the East exit and go south (I think the area is called Six Isle Canyon or something, I can't remember). Anyway, navigate through the area and you'll eventually reach Dotted Hole. To enter Dotted Hole, use Cut on the doorway.

Well, to get the second password, you need to go to Dotted Hole. While standing in front of the door, use Cut, and the door should open. Once inside, take first the top hole, the left hole, the right hole, then the bottom hole (I think.) If there's a scientist guy blocking your way, make sure you've completely cleared Icefall Cave on Four Island. That includes the helping Lorelei defeat the Rocket Wimps.

To get to the second password,go to six island and head to the dotted hole. Use CUT on the door to get in. Go straight to the hole in the hole in the midle of the room. there will be four holes in that room. If you go down all four in A speciffic order, you will end up in a room with a ruby. (you will know if your doing the right order because you'll end up in the same room each time) once you get the ruby, a scientist will snatch it, but he will tell you the password. N.J.
