Rec Room (Super Mario 64 DS)
From the Super Mario Wiki
The Rec Room is a special area found inside Princess Peach's Castle in Super Mario 64 DS. This room, located in the second floor to the right wing, features a drawer of colored boxes, every one containing a minigame that the heroes, Mario, Yoshi, Luigi and Wario reveal as they catch the Rabbits running around the castle, holding the keys that open the drawer's boxes, after talking to Toad in that room. A Toad looks after the room and hosts the minigames whenever the player wants to play in the Rec Room. Each character has 9 minigames. Two are for the characters themselves and the other seven are unlocked by catching rabbits, making it a total of 36. The room contains other things like a piano, some Koopa Shells, Blocks, Bob-omb toys and Stars around, and a Mushroom-styled table near the entrance of the room. Most of these minigames are reused in New Super Mario Bros. There is also the painting of the course Sunshine Isles, and in the back of the Rec Room is the door to Peach's Bedroom, which contains the entrance to the Goomboss Battle portrait, where one of Luigi's rabbits is located. The soundtrack that plays in the Rec Room is the Grass Land map theme from Super Mario Bros. 3.
