What a crazy, or rather, Mashuga, family.
The Mashuga family are a young couple, Frankie and Sylvia Marie, in The Sims: Livin' Large. They live in an octagon-shaped house in Neighborhood 2 and are the only pre-housed Sims in that neighborhood. They did not make it to The Sims 2, as The Sims 2 is set 25 years later and in a different neighborhood. It is considered that Frankie and Sylvia Marie either both died in Pleasantview, or didn't move from Neighborhood 2 to Pleasantview.
Mashuga is a Yiddish word for 'tacky' or 'crazy', possibly alluding to the couple's novel decor.
