Bad-Breath Express
From the Super Mario Wiki
The Bad-Breath Express (as Bowser calls it) is a locomotive operated by Bowser that appears in the game Mario Party 8. It appears exclusively on the Shy Guy's Perplex Express board.
The Bad-Breath Express will appear whenever a player lands on a Bowser Space, replacing the train's current locomotive, which could be either Shy Guy's standard one, or Donkey Kong's Barrel Train. The first player who reaches Bowser's locomotive will be forced to give a Star to him. However, if the player doesn't have any Stars, Bowser will reward them with ten Coins.
The Bad-Breath Express will leave either after someone reaches it, or if somebody lands on a DK Space.
