It definitely should not be creating any tetrahedral elements.  If it 
is, that is certainly a bug.  Are you sure that it is creating 
tetrahedral elements and not quadrilateral ones?  The mbskin utility 
might be creating the quadrilateral elements that define the skin of the 
mesh.  If that is the case, you can use mbconvert to remove those from 
the file:
   mbconvert -3 input.vtk output.vtk
