Scritters are common vermin that are usually found underground. They tend to nest in dark places and come out only to feed. Their main source of sustenance is Phazon, a weakness pirate slaves use against them. Scritters will often be caught in simple traps set out by the starving pirate slaves who then feed on the small creatures. But the pirates rarely have the last laugh, as some internal organs of the Scritter will release a toxic fluid when bitten. Those who become violently ill because of this are often said to have a case of "the scritters."
