Smog Sewer

Smog Sewer is the fourth stage of Spark the Electric Jester.

Landscape
Smog Sewer's landscape is comprised mostly of red and beige architecture, which is supported by blue bricks with meshing, and green pipes. In the background are large orange fans. A lot of the sewer is grungy looking, with dirty water near the bottom.

Smog Sewer's use is to clean the dirty water and filter it into the ocean as clean water. Due to the method used to remove some of the residuals from the water (i.e. filtering and then burning them), it somewhat contributes to Smog City's smog problem.

Level Architecture
Smog City's main gimmick is the fact that a lot of it is spent underwater. Being underwater doesn't kill you or drain any air meter (despite being dirty water), but it does make your movements floatier, so keep that in mind. There are a few varieties of enemies in this stage, so they're not that much of an issue (even if they're a step up from the usual enemy types). Sometimes, there'll be Water Columns that'll make you float up to new heights, which is required to complete the stage. Around the halfway point, you'll drop down into a battle against Skiddy-Biddy. Once it's over, you can progress through the stage, which is fairly identical in its first half when it comes to challenges. The end of the level is blocked off by Samuku. Once you defeat Samuku, you can hit the Level Clear Sign and move to the right to get to Smog City.

Fark's Story Differences
There are quite a few changes in Fark's version of the level. First is the minute change of some of the enemy layouts being trickier. Secondly, it has the addition of B-Buffs, who were previously only seen in Spark's version of Megaraph Fortress. They can be a good help to your Static Gauge if you're skilled enough, but if not, make sure to avoid them. Lastly, once you defeat Samuku, you're then thrust into a battle with another Hellhound.exe.

Trivia

 * During an early demo, the music of the stage was different, being an edited version of the final theme.
