Castle Quill is a location in the Smurf Forest that appears in the cartoon show episode "The Enchanted Quill". It is where the episode's titular quill is located, protected by fire-breathing griffins. Gargamel, Azrael, and Scruple visited this place, with the Smurflings following them, in order to find the quill so that Gargamel would have a map that would lead him to the Smurf Village, and that Scruple would easily pass his re-entry exam at the Wizard's School.
