If a narrow Theta+ pentaquark exists, it is likely that a ud s-ud triquark-diquark configuration is a significant component of its wave function. If so, the mechanism responsible for the binding of a triquark and a diquark is also likely to bind the triquark to an s antiquark. We discuss the expected properties of such a ud s- s tetraquark meson. In particular, we point out that for a 0+ isoscalar ud s s meson the lowest allowed decay mode is a four-body K K pi pi channel with a small phase space and a distinctive experimental signature.
