The Bowser Express is a level looking similar to a traveling Circus. It is home tom many enemies, and is the only level in the game that is World-Train.
- Green Star 1: The first star is on the train near the beginning of the level. Be quick to jump up and grab it.
- Green Star 2: The second star is a coin catch. Jump through the green star and collect the green coins for the star.
- Green Star 3: The last star is just before the green pipe leading out. Jump down to the little platform and kill the fire guy and nab the star.
