Oceanus is a mammoth mystical sea serpent, that when caught, was said to be so large that its meat could serve the entire population of Zork for all time.

Oceanus is also the name of a lazy titan in the once-popular sitcom, All-Father Knows Best, who just laid around in his sea-bed all day until his wife Tethys came in and announced that she was going to get a job singing with a dance band.
