The first password you get from polygon-Z, he is inside the locked room. Talk to the skorupi that is inside the park and he'll tell you how to find a switch to unlock that door, go through that now unlock door and talk to polygon-z and beat his skill game and he'll give you the 1st password. The second password you get from togekiss. To find her 1st you have to talk to bronzor, he's near the skorupi that you talked too earlier. He'll tell you to climb the pyrimd and hit the switch that's on top, but before you can climb the pyrimd you have to battle elective(just use dash and irontail and it's an easy win), then he'll let you climb the pyrimd. After hitting that switch the fire that's on the left side will go down, cross that pathway and go inside the box kart thing and it will take you to togekiss, beat her skill game and she'll give you the 2nd pasword. The third password, snorlax has. He is back in the grantite zone so just go talk to him and he'll just give you the password without having to do anything.
