Second Course (Impossible Pack)
From the Super Mario Wiki
The level begins with Mario having to go downward while avoiding Spike Tops and Fire Bars. The next area features several rotating block platforms, some with Fire Bars, followed by a wall jumping segment leading to the Checkpoint Flag.
The next section of the level is accessible by wall jumping up after the Checkpoint Flag. This area features several rotating platforms and Fire Bars, with some platforms featuring Spike Tops and many of them featuring several Flame Chomps. Mario must climb up the rotating platforms after reaching the end of the room. Several Fire Bars are placed before the Goal Pole.
