It's at the top of the flight of stairs on the second floor.
if you get all the glowing rabbits, it will unlock for a secret star. (sigh)
Once you get enough shine coins, go through the second special door. The four special doors are to the right of the level creation portraits. You have to go through a secret passage to get in. The secret passage is located to the northeast of the level creation room. When you go through the door, you immediately come out as Luigi. Obviously, he mugged Mario and switched places with him before anyone could notice. :)
After you beat the first mission in the level, go to the second floor, go to the room on the right. When in the room, go by the ability box, look at the door, then look above it. You'll see a door. to get to that door you'll need Mario. When you have Mario, look at the wall at you right at a forty five degree angle. Double jump at that wall at the angle, then jump off of it. If you get right you'll be on the platform. Go through the door and goo through the door in front of you. after you beat big boo, try to find a way to get the star. sorry that's all im saying.
you have to do in game things to unlock the door so... Giving the passwords wouldn't work
You have to get enough stars to unlock the star door(the one where peach is crying out for Mario) and when you beat Bowser you'll get a key for the basement type area. To get there you go through one of the doors underneath the stairs and go down the stairs there and unlock it.Then you get enough stars to unlock the next star door and then you beat Bowser again and then you will get a key for the door leading to the third floor,or second floor in your case.
Defeat bowser in the star door Defeat bowser in the star door
First, you have to unlock the basement by completing 'Bowser in the Dark World' (get 12 stars first). Then, in the basement, you have to unlock the second floor by getting 30 stars and completing 'Bowser in the Fire Sea'. Then, to unlock the top floor, obtain 50 stars and go up the set of stairs on the second floor. Go through the door and you are now on the top floor. (Get 70 stars to get up the endless stairs to 'Bowser in the Sky', complete the level and you have won the game). Result!
It's at the top of the flight of stairs on the second floor.
Its in a door on the bottom right corner i believe its on the second floor.
To get to the door, go straight up through the door in the lobby to the spiral staircase to get to the second floor. It's through one of the doors on that floor.
with flurrie you blow your poster on the top staircase left of the top door
YOU get the cube to unlock the other door
You will have to speak with Toad to unlock a quest in which you catch rabbits. Once you have completed this quest, you can use the white door for Super Mario 64 DS.
in order to save Mario go to the first floor and go to the door on the right and go to the door with an eight on it enter it and look for the X on the touch screen. enter it and there is a huge gomboss. kill him by swallowing the egg by pressing R. throw it at him three times and he will explode. then there is a Mario key! Good luck!
300 floor of the empire state building it needs a key of the gods to unlock the 300th floor
you have to get one star, and then go to the second floor of the castle. Go to the door with a "1" on it and it also has a white frame around the door. go in there and talk to toad. exit the castle and hit "A" when you get near a bunny. he will talk and give you a key. There are 5 rabbits total outside at first, as you go through the game, you unlock more rabbits. I have gotten 119 bunnys so far, and i have 119 keys too.
