Scritters are creatures found on the Pirate Homeworld. They live in dark areas and only come out to feed on Phazon. Most of them contain a toxin within their organs that is released when bitten. They are often found in large swarms. Due to their small size, they cannot be locked onto. It is known that Pirate Militias, most likely due to malnutrition, tend to feed on these creatures by catching them in simple traps. But of course, the poison that they excrete often make the desperate Pirates ill; they are said to be suffering from a case of the "the scritters".
