The scarabs of Tanaris have very hard shells!  Hard enough to use as a building material for lots of things.  So many things!$B$BIn fact, those shells are so useful... the scarabs were hunted all to near extinction!$B$BI know where there are more scarabs, and if you promise to bring me their shells then I'll tell you where they are.  Promise?$B$BOk, the scarabs have a colony in Zul'Farrak.  I guess the trolls don't hunt them for their shells.$B$BBut you can!  Go to Zul'Farrak and get me uncracked shells!
