Ghhhk are arboreal organisms indigenous to Clak'Dor VII, where they rise with the dawn to vocalize their screeching mating calls across the jungle terrain. They are used by the local Bith populations for the purpose of 'milking' oil from their skins, which is often used as a healing salve.
They are most notable for being represented as one of the many holomonster playing pieces in the board game of dejarik.
