Bad-Breath Express
- “Welcome to my Bad-Breath Express! Now cough up a Star! Even hobos like you gotta pay up!”
- —Bowser, Mario Party 8
The Bad-Breath Express is a locomotive operated by Bowser that appears in Mario Party 8. It appears exclusively on the board Shy Guy's Perplex Express, and it bears resemblance to the Koopa King from Mario Kart: Double Dash!!, similar to how the Barrel Train resembles the kart of the same name.
The Bad-Breath Express appears 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. In Battle Royale and Tag Battle, the first player who reaches Bowser's locomotive is forced to give a Star to him. However, if the player does not have any Stars, Bowser gives them ten coins. In Duel Battle and Star Battle Arena, Bowser steals half of the player's coins. If they have no coins, Bowser gives them ten coins.
The Bad-Breath Express leaves either after someone reaches it, which replaces the Bad-Breath Express with the normal locomotive, or if somebody lands on a DK Space, in which case the Barrel Train replaces the Bad-Breath Express.
