Princess Peach's Castle Courtyard is the beginning level of Super Mario 64 and Super Mario 64 DS. There are no enemies, and it is just a simple grassy area that Princess Peach's Castle is on. To the right of the start of the level is a small pond, and to the left is just a grassy area. Once the player obtains all of the one-hundred twenty (one-hundred fifty in the remake) stars, a cannon appears in the courtyard, which gives the player access to the top of the castle where Yoshi is located in the original. In the beginning of Super Mario 64 DS, Yoshi must first catch a rabbit to get a key for the front entrance door.
In the remake, the part of the courtyard with the Boos, a Star can be obtained if the player finds the 8 Boos with the Red Coins.
