Despite recent evidence indicating the existence of a new self-dual six-dimensional superstring, no satisfactory worldsheet formulation of such a string has been proposed. In this note we show that a theory built from Z(4) parafermions may have the right properties to describe the light-cone conformal field theory of this string. This indicates a possible worldsheet formulation of this theory.
