'''The Princess's Secret Slide''', referred to as '''Princess Toadstool's Secret Slide''' by a [[sign]], is one of the secret [[level]]s in ''[[Super Mario 64]]'' and ''[[Super Mario 64 DS]]'', as well as being one of the three [[Slide (Super Mario 64)|slides]] in the games. The entrance to the course is in the [[Peach's Room|Princess's room]], located behind the [[★ door]] marked with a "1" on the mezzanine of the [[Peach's Castle|Mushroom Castle]]. Inside the room are three stained glass windows with images of [[Princess Peach]] on them. [[Jump]]ing into the one on the right leads to the slide. In ''Super Mario 64 DS'', the room is expanded to include the locked doors with [[Mario]], [[Luigi]], [[Wario]], and a [[Power Star]] behind them, and the number of stained glass windows is reduced from three to two, but the stained glass window on the right still leads to the slide. The level is also used as one of the four courses in the [[Super Mario 64 DS#VS mode|VS mode]].

The player starts in a room with a [[Blue Coin Block]] to the right. Once the player enters the slide ahead, a timer begins. The slide first takes the player down a large tunnel, which leads to a steep downward slope. After a large 270-degree bend is a series of drops with a [[1-Up Mushroom|1-UP Mushroom]] in this area followed by several bends, ultimately leading to the final room of the slide. If the player falls off the slide, they will be brought back to the lobby of the castle with no life lost. In the VS mode course, the first Power Star can be found at the start, the second is in the middle of the slide, and the last three are in the final room.

This is the only secret course that contains [[Blue Coin]]s, and the only course that has no [[Red Coin]]s in the original game.

The player must ride the slide all the way to the bottom and hit the [[! Block|yellow block]] to collect the Power Star.

This Star will appear only if the player reaches the bottom of the slide in under 21 seconds. The Star will appear in front of the yellow block that contained the first Star.

This music has since been arranged in multiple future titles in the [[Super Mario (franchise)|''Super Mario'' franchise]], including the [[Super Smash Bros. (series)|''Super Smash Bros.'' series]] (''[[Super Smash Bros. Melee]]'' and ''[[Super Smash Bros. Brawl]]'' as the main track for the [[Rainbow Cruise]] stage, combined with the [[Underwater Theme]] from ''[[Super Mario Bros.]]''); ''[[Super Mario Galaxy 2]]'' in the [[Tall Trunk Galaxy]] mission [[Tall Trunk's Big Slide]] and in the [[Rolling Coaster Galaxy]]; ''[[Paper Mario: Sticker Star]]'' during the minecart sections in [[Bowser's Snow Fort]]; ''[[Super Mario 3D World]]'' while the player rides [[Plessie]], which was reused in ''[[Captain Toad: Treasure Tracker]]'' during part of the [[Coins Galore]] minigames; and ''[[Mario & Sonic at the Sochi 2014 Olympic Winter Games]]'' and ''[[Mario & Sonic at the Rio 2016 Olympic Games]]'' as one of the tracks that can be played in events, which is [[Toad]]'s theme in the latter game. The original song is also featured in ''[[Super Smash Bros. for Wii U]]'', ''[[Super Smash Bros. Ultimate]]'', and ''[[Super Mario Maker 2]]''.

*After [[Mario]] gets the first Star from the [[Bob-omb Battlefield]], the message that appears erroneously says that the entrance to this secret level is on the second floor, while in fact it is on the mezzanine.
