In the movie Coneheads, The Garthok is a six-limbed giant animal native to Remulak. These taloned, tusked, and single horned beasts emerge every Zerl, or Remulakian Year, specifically when the three moons of Remulak align. During this time of Zerl the Remulakians or Coneheaded aliens bring forth criminals to fight the garthok, in order to get a reprieve from their crimes. Considering the size power and Ferocity of the Garthok, and how most Remulakians who were to face the Garthok in the film "Coneheads" ended up mutilated, it can be assumed that it is rare for a Remulakian to regain his freedom.
