moose in a mansion

A moose in a mansion simply means that a moose named Nate is standing quite flatly in a moose named Drew's mansion. It's often a part of an old polish language with such phrases. Often you may hear "a yellowfin in a penthouse". We do not know how these moose met or how the moose commonly named Drew aquired a mansion of such standings.
