Stop that train! (Go to the cellar!!)
From the Super Mario Wiki
Stop that train! is the third story of an additional chapter two in the game Wario Land II. It takes place on an underground railroad track connecting Wario Castle with a cave near Maze Woods and is one of the two train-themed levels (the other one being 4-1).
The player starts at the left side of the train and has to make his way to the far right, thereby avoiding traps and enemies. To progress, the player also has to explore the rooftop of the train, where movement is more difficult because of the heavy winds. In the last wagon on the right, Wario can find a lever that triggers the train's breaks. The level is cleared after the lever has been pulled.
Hidden Treasure: Moon Emblem
The hidden treasure of this level, the Moon Emblem, is located in a separate wagon of the train. In order to reach it, the player has to have Wario fall in the big gap right before the final one on the rooftop. Wario will end up in a wagon full of traps. The player should head right, sneak past the blades and he will reach the treasure door.
