|<< Directory of levels >>|
The player starts the level on the bottom-right portion of the map. At the top-left is Donkey Kong who will periodically throw Poison Mushrooms into the area, and Donkey Kong Jr. who will occasionally pull a switch to make the walls and bridges in the area appear and disappear. Mario must first get across the Conveyor Belt at the bottom while crouching to avoid the spikes. After climbing a ladder, Mario must move across the next set of Conveyor Belts while avoiding Gyātoru, then climb two more ladders and wait for the bridges to reappear to head left and reach Pauline.
