World 5-2 (Super Mario Bros. 2)

World 5-2 is the second level of World 5 in Super Mario Bros. 2.

Layout
This level is set mostly on land, unlike the previous stage; there aren't many obstacles, so most of the difficulty is based on the diversity of enemies (such as Hoopsters and Porcupos) found. At some point, a large mountain must be climbed through various vines, then the player has to fall through a deep hole full of spikes, which can only be avoided with quick reflexes. Birdo is fought over a cascade.

Trivia

 * In the Super Mario All-Stars and Super Mario Advance ports, this is the only level in World 5 to be set at night unlike the NES version where its three levels are all set at night.
 * In the drop area where the player must grab the POW Block to advance on and head to the door leading to the battle against Birdo, the underworld BGM plays in that area in the original NES version (as well as Doki Doki Panic) despite being still outside. This was corrected in the Super Mario All-Stars and Super Mario Advance ports where the overworld BGM would still play after entering that area.
