Super Mario 64/Secret Castle Stars

There are 15 secret castle stars which do not appear in regular courses.

Toad Stars (3)
Three stars are given by Toad, the mushroom. The first is in the basement, in the room with Hazy Maze Cave. Talk to Toad and he will give you a star. The next star is on the second floor in the castle. This Toad is located under the stairs. The last one is on the third floor next to the Tick Tock Clock.

The Princess' Secret Slide (2)
In the castle's main room, go up the stairs and to the right. Enter the door. Inside you will find a room with three glass paintings. Jump in the right one.

There are two stars in this level:


 * 1) One is at the bottom of the slide
 * 2) Another is awarded if Mario finishes less than 21 seconds.

To complete the slide in the fastest time possible, fall off at the first bend (about 8-9 seconds into the slide). You will land on the track far below. With this shortcut it is possible to save 3 seconds. Also, remember to hug the inside of the track as it turns.

The Secret Aquarium
In the room where you enter Jolly Roger Bay, go to the right and backflip into the hole in the wall. Collect the eight red coins.

Wing Mario Over The Rainbow
In the room with the Tick Tock Clock level, go to the left and enter the hole in the wall. Collect the eight red coins. This is one of the hardest stars in the game. If you fall down from this level you will not lose a life; instead, you will end up outside the castle.

Mips the Rabbit (2)
After you have 15 stars and less than 50 stars a rabbit can be seen hopping around the basement. Catch him and he will give you a star. He will return after you get more than 50 stars and can be caught again for another star. It is possible to catch him again, though he will not give you any more than two stars total.

Bowser levels (3)
Collect eight red coins in all three Bowser levels:
 * The Dark World
 * The Fire Sea
 * The Sky.

Cap switch levels (3)
Collect eight red coins in all three cap switch levels
 * Wing Cap
 * Metal Cap
 * Vanish Cap.
