you need to get the key from bowser in the basement
Sadly, no, there isn't. The only ? box that isn't in a level is the one on the castle roof.
Get the first star then go back in.
when you go to the bottom floor of the bathroom!
second floor left in 3D
You must have 50 stars to enter the third floor of the castle. When you claim the spiral stair case after defeating Bowser 2 turn right and jump through the painting this will take you to the 3rd floor.
To reach the roof of Peach's Castle in Super Mario 64, you need to collect at least 70 Power Stars. Once you have enough, go to the castle's entrance and look for a painting of Bowser in the Sky on the second floor. After entering that level and defeating Bowser, you'll unlock the cannon outside the castle. Use the cannon to shoot yourself to the roof, where you can find Yoshi waiting for you.
to get to the mirror room you have to go through the door on the top floor of the castle. then you go in one of the doors with a star on it!!! :)
To get to the top of the castle on Super Mario 64, there are two ways. The first is to get a running start (running towards the right side corner of the castle), jump on the castle wall, then on the grass, then back on to nearly grab onto the edge, and get on top of the castle. The second way is to get all of the stars, then a cannon will be accessible out on the front part of the castle. Then, climb into the cannon and shoot yourself on top of the castle.
Yoshi is on the castle roof in Super Mario 64. Three lives and a flying cap box are also up there.
It's at the top of the flight of stairs on the second floor.
Yes!
You have to complete the world five castle as mini mario.
