We show that there exist infinitely many non-invertible, hyperbolic knots
that admit toroidal Dehn surgery of hitting number four. The resulting toroidal
manifold contains a unique incompressible torus meeting the core of the attached solid
torus in four points, but no incompressible torus meeting it less than four points.
