Scrubber

Scrubbing Bubbletrons are enemies that appear in all three sewer levels in the games Crash Bandicoot 2: Cortex Srikes Back and Crash Bandicoot: The Huge Adventure.

Appearance
The machines are generally red-brown and white in color with large eyes and an antenna coming out the top. They have an N emblazoned on their front suggesting they were made by Cortex to clean up the sewers and have brushes on the bottom to clean up messes.

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.

Trivia

 * In the prototype of Crash 2, Bubbletrons would appear around corners, taking Crash by surprise.
