  In this work we are revisiting the well studied Ellis wormhole solution in a
generalized Horndeski theory motivated from the Kaluza-Klein compactification
procedure of the more fundamental higher dimensional Lovelock gravity. We show
that the Ellis wormhole is analytically supported by a gravitational theory
with a non-trivial coupling to the Gauss-Bonnet term and we expand upon this
notion by introducing higher derivative contributions of the scalar field. The
extension of the gravitational theory does not yield any back-reacting
component on the spacetime metric, which establishes the Ellis wormhole as a
stealth solution in the generalized framework. We propose two simple mechanisms
that dress the wormhole with an effective ADM mass. The first procedure is
related to a conformal transformation of the metric which maps the theory to
another Horndeski subclass, while the second one is inspired by the spontaneous
scalarization effect on black holes.
