Gobias Koffi is living in a modern house at the beach and is quite rich. He works as a Fertilizer Analyst in the Science Career. There's not much known about his family, we only know his deceased father was named Gaylord Koffi, who is buried at Pleasant Rest Graveyard. It implied that he is a homosexual (perhaps the first premade in the The Sims series).
Trivia
Gobias Koffi's name is a reference to the actor David Cross's character, Tobias[1], on the now-cancelled FOX show, Arrested Development. At one point, Tobias and his brother-in-law, G.O.B., decide to start a business, and come up with the name "Gobias... as in, go buy us a cup of coffee", hence Gobias Koffi. In the series, his many homosexual tendencies were a running joke in the show; he made frequent sexual double-entendres to which he seems completely oblivious, convincing his entire family that he was gay without actually being so. It is unknown if this is the same case with Gobias. Gobias also has the Never-Nude trait, a term coined by the show's writers to describe one of Tobias's disorders, and he bears something of a physical resemblance to David Cross, the actor who portrays Tobias in the series.
His house is one of the only ones (other than the Langerak household) to have a special plant. Maybe because he works as a fertilyser analist and this job grant him free special seeds.
