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 explores Cortex Island's sewer again. This stage introduces triple-bladed fans that spin too fast for Crash to slip through unharmed. The player must take out the blades first by spinning the scrubbing bubbletrons into them.
