Party Cube

The Party Cube is a giant white box found in Mario Party 4. In the game, Toad, Shy Guy, Boo, Koopa and Goomba sent invitations to Mario and friends, allowing them to enter the Party Cube. Inside the Party Cube are a lot of game boards and tons of fun.

Mario, Luigi, Peach, Yoshi, Daisy, Donkey Kong, Wario and Waluigi were allowed to enter the Party Cube. Inside the Party Cube, everyone partied and received a lot of presents.

During Mario Party 4's credits, the story of how the game's hosts found the Party Cube is slowly revealed through a nostalgic-looking slideshow. Apparently, they came across it as a big, blank block, and naturally carved pictures of themselves in it, which led to a series of events that slowly "morphed" them into their Mario Party 4 forms. The Party Cube was last seen escaping into the stars, being chased by the hosts.
