Scrubber

Scrubbing Bubbletrons are enemies that appear in all three sewer levels in the games Crash Bandicoot 2: Cortex Strikes Back and Crash Bandicoot: The Huge Adventure. Being the generic enemy in the sewer levels, they can be defeated using any attack.

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 just like vacuums.

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, but are most useful for destroying the turbines of the fans that spin way too fast.
 * In Hangin' Out, a conveyor of Bubbletrons try to hurl themselves at Crash until he gets to the end of the tunnel.

Trivia

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