Sewer or Later

Sewer or Later (ボワボワ さぎょういん lit. Scorching Worker in Japanese) is the twelfth level and is the second level of the the third warp room in Crash Bandicoot 2: Cortex Strikes Back. In this level, taking place later than The Eel Deal, Crash Bandicoot explores Cortex Island's sewer again. This stage introduces triple-bladed fans that spin entirely too fast for Crash to slip through unharmed; the player is supposed to take out the blades first, by spinning the scrubbing bubbletrons into them.

If the player has obtained the yellow gem from the previous level, Plant Food, they can access this stage's secret yellow gem path, a sinister series of challenging jumps simplified only by the fact that the only necessary item on said route, a clear gem, is located early on so there is literally no reason to traverse the whole path and the player can just kill themselves after getting it. A split path later on in the main body of the level awkwardly requires the player to take the right path just long enough to reach the ! crate, then backtrack to the left path to break the crates it created (and collect the crystal), then backtrack again to take the right path again to finish off the level.

 * Spin the bubble robots to open up the pathway.

Trivia

 * "Sewer or Later" is most likely derived from the phrase "sooner or later".
 * This level also introduces the flamethrower lab assistant, which is from here on in the sewer levels.
 * This is the only level out of the sewer levels in Crash 2 where there are no wire meshes. In Crash Bandicoot: The Huge Adventure, Just in Slime also has no wire meshes.
 * This was the first non-boss non-warp-room level during the development of this game. It is also the one with the most redesigns.
 * In the leaked beta version, this level had an extra TNT crate and two fewer Aku Aku crates.
