Rat

Rats are enemies encountered throughout the Crash Bandicoot series. They can be seen wandering around aimlessly in dark, loomy places such as Cortex Castle, ruin levels, etc. They are sometimes stationary or they move back and forth on a set path in Crash Bandicoot 2: Cortex Strikes Back. Notably, rather than squeaking they make a snarling sound as Crash approaches them.

Rats were seen again around the Academy of Evil in the Boiler Room on a much more larger scale than in their first appearences.
