Super Mario 64/Secret Castle Stars

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

Toad – Three Stars
Toad will give you three free stars just by talking to him. The following is a list of where to find all three of these stars:
 * 1) In the basement in the room with Hazy Maze Cave
 * 2) On the second floor just under the stairs leading up to the third floor
 * 3) On the third floor next to the Tick Tock Clock.

The Princess' Secret Slide – Two Stars
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 one to your right.

There are two stars in this level:


 * 1) At the bottom of the slide
 * 2) Awarded if Mario finishes the slide in less than 21.0 seconds

To complete the slide in under 21 seconds, make sure to hug all of the corners. Do your best to never slow down by not hitting any walls.

There is a trick to completing the slide in even less time. When you reach the first corner, bump into the wall to turn yourself backwards (there is a coin that you can aim for to do this effectively). Note that it will take practice to do this properly. Now that you are sliding backward, bump into the railing on the right side as the walls end to bounce toward the left side of the slide. Immediately jump off of the left side and kick just as you reach the bottom of the slide level. It is possible to complete this slide in under 15 seconds.

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 in this aquarium for a star. There are four red coins along the floor and four red coins between a circle of yellow coins halfway to the top of the level.

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 in this level. 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. The following is a list of where all eight coins are:


 * 1) Once you start off, do a complete 180 to find a coin directly behind you.
 * 2) Find a pink platform nearby and land on it. Grab the wing cap and follow the rainbow to a cloud for the second coin.
 * 3) To the left will be another pink platform with a pink Bob-Omb. Grab the coin here and open the cannons.
 * 4) Jump in the cannon and aim it at a cloud that has many rainbows connecting to it, next to a blue cloud. Aim a little higher than these and shoot yourself to the cloud for the fourth coin.
 * 5) Head back into the cannon you just came from. Turn left and aim yourself above the next pink platform and shoot to land on it.  Jump into the cannon here and aim above the blue cloud you saw before.  You should fly right through it, grabbing the fifth coin in the process.
 * 6) Maneuver to the left and grab the green poles hanging off of a cloud. The sixth coin is here.
 * 7) Slide down and drop off the pole. Near you is another cannon.  Jump in and aim above the cloud with the poles. Shoot yourself off and you'll find the last two coins.

Make sure you always replenish your wing cap when you can, so that you don't lose it in the middle of flying around.

Mips the Rabbit – Two Stars
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 gain 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 – Three Stars
Collect eight red coins in all three Bowser levels:
 * The Dark World
 * The Fire Sea
 * The Sky.

Cap switch levels – Three Stars
Collect eight red coins in all three cap switch levels
 * Wing Cap
 * Metal Cap
 * Vanish Cap.
