Pygmy slurks are the invention of Vakkler's brother. They are highly intelligent (for slurks), and generally used by kobolds as sheepdogs are used by shepherds. They are fairly popular as pets, though not with kobolds (who do not keep pets).
An abnormality found in some pygmy slurks is that they possess a special addition in their throat which allows them to emit a high-pitched keening sound. This sound is very sympathetic and is painful to creatures with advanced hearing.
Pygmy slurks possess slime glands as large as fully-sized slurks.
