Scrubber

The Scrubbing Bubbletrons appear in all three sewer levels in the game Crash Bandicoot 2: Cortex Srikes Back.

Appearance
The machines are generally red-brown and white in colour with large eyes and an antenna coming out the top. They have an N emblazoned on their front and have brushes on the bottom to clean up any mess from them darn bandicoots. Despite being robotic, some of them do seem to regenerate.

Types
Bubbletrons perform different functions in each level:
 * Scaling pipes in a circle, in Sewer or Later three bubbletrons scale the pipes in a spring-like fashion. They can also be used as 'fodder' to destroy nearby turbines.
 * In Hangin' Out, a conveyor of bubbletrons try to hurl themselves at Crash.

Defeating the Bubbletron
Being the generic enemy in the sewer levels, they can be defeated using any attack possible.
