Deep Sea Research is the second level of World 3. An underwater stage with a screen darkening gimmick, and filled with a large amount of jellyfish.

Level overview[]

Begin the stage by following the set path, dodging the enemies along the way. Be careful for Jelectros hidden behind the darkness. You'll soon find a rainbow-colored jellyfish. Collect it to restore Mario's sight. 

Keep proceeding right, dodging Jelectros along the way. Look for an opening in the floor and collect the two rainbow jellyfishes you come across. Head right still, and you'll come across a field of Jelectros. Proceed carefully to catch the rainbow jellyfish, while still dodging the Jelectros. 

After a few screens of this, you'll find the goal.

Graphics[]

For graphics, this stage uses the cave foreground from Super Mario World 2: Yoshi's Island, and the underwater background from Donkey Kong Country.

The Jelectros use their sprites from the All-Stars version of Super Mario Bros. 3.

The rainbow jellyfish's sprites seem to be original.

Music[]

The music used in this level is Boundaries from Romancing SaGa 3.
