Scrubber

Scrubbing Bubbletrons are enemies that appear in all three sewer levels in the games Crash Bandicoot 2: Cortex Strikes Back, Crash Bandicoot: The Huge Adventure, and the N. Sane Trilogy remaster of the second game. 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.

Appearances

 * Crash Bandicoot 2: Cortex Strikes Back
 * Crash Bandicoot: The Huge Adventure
 * Crash Bandicoot N. Sane Trilogy
 * Crash Team Racing Nitro-Fueled

Trivia

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