First Course (Impossible Pack)
From the Super Mario Wiki
Through the Warp Pipe at the end is a sky-themed segment. Mario must traverse by moving on a paddle wheel while Crowbers attempt to attack him. After the Checkpoint Flag, there are Warp Pipes which drop Bob-ombs onto the platform. After this is a pair of Lakitus which drop Spinies. The pipe leading to the next area is a distance away from where the platform stops.
