Princess Peach's Castle/Rec Room

The Rec Room is a room found in Super Mario 64 DS, accessed in the room that leads to the Princess' Secret Slide and the character doors. It is a colorful room filled with props.

The room has a Toad in the center, who must be talked to in order to make the Rabbits begin to appear. The keys the Rabbits dropped can be used in the Rec Room in order to play minigames.

The Rec Room has the painting to Sunshine Isles, as well as an 8-star door that leads to a room believed to belong to Princess Peach. It contains a glass window that shows Peach's Balcony, a couch, and the entrance to Goomboss Battle.

Waluigi Connections
The doots in this room on the floor are red for Mario, green for Luigi and Yoshi, and yellow for Wario. However, there are also purple dots. Some believe that this implies Waluigi's existence.

Peach's Balcony
Peach's Balcony is a balcony that can be seen through a window in the smaller room in the Rec Room. It cannot be accessed, though some have theorized a possible way to reach it.

Super Mario 64 Manifestation
The Rec Room has been reported to appear in some personalized copies of Super Mario 64. They usually only contain the entrance to Sunshine Isles, and has a star-giving Toad, as well as the Goomboss Battle entrance. It is believed the minigames are not included due to lack of space on the cartridge.
