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.
The stamp above the little room you enter right after you get the second star. Jump on the second ? block and do a ground pound. It will raise a platform and take you to the top to get your stamp. Be quick! As the screen moves.
