Bowser Game Hall
From the Super Mario Wiki
Bowser's Game Hall.
The Bowser Stadium is one of the places in Mario Party Advance. That is located in the Seaside area of Shroom City, but can only be accessed through the Pipe House.
When the player decides to stop here, they will meet Bowser and his cohort, Koopa Kid. Their quest, Game King, involves the player playing Bowser's mini-game, Watch 'Em. Success will earn the player the right to keep the game.
